Buying Composite Laser Crystals

Related product category: optical bonding services or machinery

Composite laser crystals (or hybrid laser crystals) are laser crystals fabricated by combining different parts. For example, there are laser rods where only the center region is doped, or where undoped regions are bonded to the ends. These designs offer advantages such as improved thermal management and optimized laser performance.

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 composite laser crystals. 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 composite laser crystals. 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.

composite laser crystals

Diffusion-bonded laser crystals are composite laser crystals consisting of two, three, or more parts crystals with different doping compositions, where the constituent parts are combined through a technique called diffusion bonding. Diffusion bonding laser crystals are usually applied to decrease thermal lensing effects, improve beam quality, and make compact laser modules.

Shalom EO offers diffusion-bonded crystals with copious composition options of combining YAG, Nd:YAG, Cr:YAG, Nd:Ce:YAG, YVO4, Nd:YVO4. A diameter range of 2–18 mm and a length range of 2–200 mm is available. Doping percentages and coatings could be tailored upon request.

composite laser crystals

The composite (or diffusion-bonded) laser crystals consist of two crystals that are fixed together to form a monolithic design. The most popular combination includes Nd3+:YAG as the laser medium and Cr4+:YAG as the passive Q-switch. Most of the composite laser crystals like Nd3+:YAG + Cr4+:YAG, Yb3+:YAG + Cr4+:YAG, Nd3+:YAG + V3+:YAG, Er3+:YAG + YAG, Nd3+:YVO4 + YVO4 are available from stock or with customer’s specifications with AR, PR or HR coatings.
