Buying Double-clad Fibers

double-clad fibers

Top-level product category: icon fiber optics

More general product categories: rare-earth-doped fibers, specialty fibers

Related product categories: triple-clad fibers, large mode area fibers, fiber optics

Double-clad fibers are active optical fibers with an additional pump cladding that accepts pump radiation with low beam quality. They are widely used in high-power fiber amplifiers and lasers, enabling efficient energy transfer from the pump light to the highly coherent laser light. They are thus acting as brightness converters.

Making Good Purchase Decisions

As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.

NEW: Structured Decision Process

Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you buy.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

To help you, we have already listed some aspects we recommend you consider when buying double-clad fibers. Of course, there may be other aspects that are relevant to your specific case.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

Otherwise, you will need to talk to your technical colleagues.

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable suppliers

We suggest three steps:

  • Below, you can find our list of suppliers for double-clad fibers. Use the checkboxes to mark possibly suitable suppliers.
  • The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
  • Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

double-clad fibers

Our ytterbium-doped double-clad fibers feature the largest single-mode cores available. They have a high numerical aperture in the pump core/inner cladding for efficient pumping, compatible with both inexpensive and high-power broad-area emitting pumps. The single-mode signal travels in the large mode area to give high power levels and prevents nonlinearities. Need it packaged? Choose one of our aeroGAIN-ROD or aeroGAIN-BASE modules.
