This double-clad fiber is not intended to be used with any of our active doped fibers.
For applications that require matched active and passive 5 fibers, we offer Yterbium doped fibers with matching passive double-clad fibers found.
Thorlabs recommends splicing DCF13 to either multimode fiber or single mode fiber 5 have compatible core diameters matching the 1 st cladding or core, respectively, of the DCF fiber.
Please note that single mode light transmitted through the double-clad fiber into a spliced multimode fiber will become multimode.
Conversely, multimode light in the double-clad fiber will not transmit to a spliced single mode fiber.

For patch cables made using this fiber, please contact with inquiries.
The right image shows the standard intensity profile of the beam propagated through the fiber with the MFD and core diameter called out.
Definition of the Mode Field Diameter The mode field diameter MFD is one measure of the beam width of light propagating in a single mode fiber.
It is a function of wavelength, core radius, and the refractive indices of the core and cladding.
While much of the light in an optical fiber is trapped within the fiber core, a small fraction propagates in the cladding.
Measurement of MFD The measurement of MFD is accomplished by the Variable Aperture Method in the Far Field VAMFF.
An aperture is placed in the far field of the fiber output, and the intensity is measured.
As successively smaller apertures are placed in the beam, the intensity levels are measured for each aperture; the data can then be plotted as power vs.
The MFD is then determined using Petermann's second definition, which is a mathematical model that does not assume a specific shape of power distribution.
The MFD in the near field can be determined from this far-field measurement using the Hankel Transform.
Quick Links Laser-Induced Damage in Silica Optical Fibers The following tutorial details damage mechanisms relevant to unterminated bare fiber, terminated optical fiber, and other fiber components from laser light sources.
A fiber component, such as a bare fiber, 5 cable, or fused coupler, may have multiple potential avenues for damage e.
The maximum power that a fiber can handle will always be limited by больше на странице lowest limit of any of these damage mechanisms.
While the damage threshold can be estimated using scaling relations and general rules, absolute damage thresholds in optical fibers are very application dependent and user specific.
Users can use this guide to estimate a safe power level that minimizes the risk of damage.
Following all appropriate preparation and handling guidelines, users should be able to operate a fiber component up to the specified maximum power level; if no maximum is specified for a component, users should abide by the "practical safe level" described below for safe operation of the component.
Factors that can reduce power handling and 5 damage to a fiber component include, but are not limited to, misalignment during fiber coupling, contamination of the fiber end face, or imperfections in the fiber itself.
Light is https://aisebijou.ru/100/kaminnaya-vityazhka-restart-cpf012168-bordo.html on this interface when free-space coupling or when two fibers are mated using optical connectors.
High-intensity light can damage the end face leading to reduced power handling and permanent damage to the fiber.
For fibers terminated with optical connectors where the connectors are fixed to the fiber ends using epoxy, страница heat generated by high-intensity light can burn the 5 and leave residues on the fiber facet directly in the beam path.
Verification of the performance and reliability of fiber components in the system before operating at high power must be done by the user, as it is highly system dependent.
Damage Mechanisms on the Bare Fiber End Face Damage mechanisms on a fiber end face can be modeled similarly to bulk optics, and industry-standard damage thresholds for UV Fused Silica substrates can be 5 to silica-based fiber.
The table to the right lists two thresholds for optical power densities: a theoretical damage threshold and a "practical safe level".
In general, the theoretical damage threshold represents the estimated maximum power density that can be incident on the fiber end face without risking damage with very good fiber end face and coupling conditions.
The "practical safe level" power density represents minimal risk of fiber damage.
Operating a fiber or component beyond the practical safe level is possible, but users must follow the appropriate handling instructions and verify performance at low powers prior to use.
Calculating the Effective Area for Single Mode and Multimode Fibers The effective area for single mode SM fiber is Удилище спиннинговое Abu Garcia Rocksweeper Nano 822H by the mode field diameter MFDwhich is the cross-sectional area through which light propagates in the fiber; this area includes the fiber core and also a portion of the cladding.
To achieve good efficiency when coupling into a single mode fiber, the diameter of the input beam must match the MFD of the fiber.
As an example, SM400 single mode fiber has a mode field diameter MFD of ~Ø3 µm operating at 400 nm, while the MFD for Нажмите для продолжения Ultra single mode fiber operating at 1550 nm is Ø10.
Please note that this calculation assumes a uniform intensity profile, but most laser beams exhibit a Gaussian-like shape within single mode fiber, resulting in a higher power density at the center of the beam compared to the edges.
Therefore, these calculations will slightly overestimate the power corresponding to the damage threshold or the practical safe level.
Using the estimated power densities assuming a CW light source, we can determine the corresponding power levels as: SM400 Fiber: 7.
For optimal coupling, Thorlabs recommends focusing a beam to a spot roughly 70 - 80% of the core diameter.
The larger effective area of MM fibers lowers the power density on the fiber end face, allowing higher optical powers typically on the order of kilowatts to be coupled into multimode fiber without 5 />Each line shows the estimated power level due to a specific damage mechanism.
The maximum power handling is limited by the lowest power level from all relevant damage mechanisms indicated by a solid line.
Fibers terminated with optical connectors have additional power handling considerations.
Fiber is typically terminated using epoxy to bond the fiber to a ceramic or steel ferrule.
When light is coupled into the fiber through a connector, light that does not enter the core and propagate down the fiber is scattered into the outer layers of the fiber, into the ferrule, and the epoxy used to hold the fiber in the ferrule.
If the light is intense enough, it can burn the epoxy, causing it to vaporize and deposit a residue on the face of the connector.
This results in localized absorption sites on the fiber end face that reduce coupling efficiency and increase scattering, causing further damage.
For several reasons, epoxy-related damage is dependent on the wavelength.
In general, light scatters more strongly at short wavelengths than at longer wavelengths.
Misalignment when coupling is also more likely due to the small MFD of short-wavelength SM fiber that also produces more scattered light.
To minimize the risk of burning the epoxy, fiber connectors can be constructed to have an epoxy-free air gap between the optical fiber and ferrule near the fiber end face.
Determining Power Handling with Multiple Damage Mechanisms When fiber cables or components have multiple avenues for damage e.
In general, this represents the highest input power that can be incident on the patch cable end face and not the coupled output power.
As an illustrative example, the graph to the right shows an estimate of the power handling limitations of a single mode fiber patch cable due to damage to the fiber end face and damage via an optical connector.
The total input power handling of a terminated fiber at a given wavelength is limited by the lower of the two limitations at any given wavelength indicated by the solid lines.
A single mode fiber operating at around 488 nm is primarily limited by damage to the fiber end face blue solid linebut fibers operating at 1550 nm are limited by damage to the optical connector red solid line.
In the case of a multimode fiber, the effective mode area is defined by the core diameter, which is larger than the effective mode area for SM fiber.
This results in a lower power density on the fiber end face and allows 5 optical powers on the order of kilowatts to be coupled into the fiber without damage not shown in graph.
Please note that these are rough estimates of power levels where damage is very unlikely with proper handling and alignment procedures.
It is worth noting that optical fibers are frequently used at power levels above those described here.
However, these applications typically require expert users and testing at lower powers first to minimize risk of damage.
Even still, optical fiber components should be considered a consumable lab supply if used at high power levels.
These limitations will affect all fiber components as they are intrinsic to the fiber itself.
Two categories of damage within the fiber https://aisebijou.ru/100/vodonagrevatel-nakopitelniy-ballu-bwhs-100-proof.html damage from bend losses and damage from photodarkening.
Under these circumstances, light escapes the fiber, often in a localized area.
The light escaping the fiber typically has a high power density, which burns the fiber coating as well as any surrounding furcation tubing.
It will then leak out over a distance of centimeters or meters instead of at one localized spot within the fiber, minimizing the risk of damage.
Thorlabs manufactures and sellswhich boasts very high, megawatt range power handling.
Photodarkening A second damage mechanism, called photodarkening or solarization, can occur in fibers used with ultraviolet or short-wavelength visible light, particularly those with germanium-doped cores.
Fibers used at these wavelengths will experience increased attenuation over time.
The mechanism that causes photodarkening is largely unknown, but several fiber designs have been developed to mitigate it.
For example, fibers with a very low hydroxyl ion OH content have been found to resist photodarkening and using other dopants, such as fluorine, can also reduce photodarkening.
Even with the above strategies in place, all fibers eventually experience photodarkening смотрите подробнее used with UV or short-wavelength light, and thus, fibers used at these wavelengths should be considered consumables.
Preparation and Handling of Optical Fibers General Cleaning and Operation Guidelines These 5 cleaning and operation guidelines are recommended for all fiber optic products.
Users should still follow specific guidelines for an individual product as outlined in the support documentation or manual.
Damage threshold calculations only apply when all appropriate cleaning and handling procedures are followed.
This ensures that focused beams of light are not incident on fragile parts of the connector or fiber, which can possibly cause damage.
Always inspect the fiber end prior to connecting the fiber to an optical system.
The fiber end face should be clean and clear of dirt and other contaminants that can cause scattering of coupled light.
Bare fiber should be cleaved prior to use and users should inspect the fiber end to ensure a good quality cleave is achieved.
Poor splice quality may increase light scattering at the splice interface, which can be a source of fiber damage.
Damage from scattered light can occur if a high power beam 5 focused on the cladding, coating, or connector.
Tips for Using Fiber at Higher Optical Power Optical fibers and fiber components should generally be operated within safe power level limits, but under ideal conditions very good optical alignment and very clean optical end facesthe power handling of a fiber component may be increased.
Users must verify the performance and stability of a fiber component within their system prior to increasing input or output power and follow all necessary safety and operation instructions.
The 5 below ссылка на подробности useful suggestions источник considering increasing optical power in an optical fiber or component.
Users should follow all appropriate guidelines to prepare and make a high-quality fiber splice.
Poor splices can lead to scattering or regions of highly localized heat at the splice interface that can damage the fiber.
The 5 power can be ramped up slowly to the desired output power while periodically verifying all components are properly aligned and that coupling efficiency is not changing with respect to optical launch power.
When operating at high power, the localized heating that can адрес страницы when a large amount of light escapes a small localized area the stressed region can damage the fiber.
Avoid disturbing or accidently bending fibers during operation to minimize bend losses.
