Buying Composite Laser Crystals
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.

 A635, Boke Mansion No. 9 Xiyuan Road Xihu District, Hangzhou 310030 China |  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. |
 Lasers, Optics, Electronics. Made in Germany. ALPHALAS GmbHBertha-von-Suttner-Str. 5 37085 Göttingen Germany |  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. |
