1520 Series - Pump Cavities
1520-Series diffuse pump cavities are designed using unique proprietary technology which allows UV and/or 1.06 micron suppression by selectively doping the reflector material for the specific application. The company offers a series of interchangeable reflector assemblies as specified. This model incorporates Titanium end caps which is recommended for high energy applications.
Maximum power capabilities are 800-1300 watt depending on size and operating conditions. A large selection of standard sizes are available as indicated. Customized configurations available on request. This Series should be considered for use with high to medium gain materials such as Nd:YAG, YAP, YSGG, GSGG, etc.
