Vigitek, Inc. designs and manufacturers pump chambers for solid-state lasers with industry's highest level of performance in terms of efficiency, pumping uniformity, lifetime and reliability. These pump cavities incorporate diffuse close-coupled design suitable for high-power operation. Power rating ranges from 800 to 1500 W. The cavity power rating can be raised to 3 kW in a custom-configuration where the reflector is cooled separately. Reflector assembly consists of glass or fused silica monoblock surrounded by several layers of ultra pure BaSO4. The body of the chamber is made from aircraft-grade Titanium alloy with virtually a lifetime of maintenance-free operation. The cavity is best suited for pulsed Nd:YAG, Nd:YSGG, Nd:YAP, Er:YAG, Er:Glass, Alexandrite and other solid-state laser media. Our power chambers have demonstrated overall efficiencies of almost 6.0% for free-running Nd:YAG laser and in excess of 3.0% for Er:YAG laser, providing very high beam quality.
