1620 Series High-Power Pump Cavities
1620-Series diffuse close-coupled ceramic pump cavities are designed for high energy applications. Maximum pump energy rating depends on cavity size and is only limited by flash-lamp life-time considerations. Reflector assembly incorporates ceramics, glass, and other inert materials. End-caps are fabricated from military-grade Titanium Alloy ensuring unlimited maintenance-free operation. This model should be considered for use with Nd:YAG, Nd:glass, and Alexandrite in high-energy, moderate repetition rate applications. Maximum input power rating varies between 700 to 1000 watt depending on size, flow rate and operating conditions. Standard sizes as specified, are available from stock. Custom configuration and modifications available on request.
