High Power Nd: YAG Mini-FPL.
Abstract
The program has encompassed the design, engineering development, and testing of a laboratory prototype device with the objective of greater than 100 watts cw multimode. In performance tests, the maximum multimode output beam power was 3000W with lamp input power of 20kW. Maximum output/input efficiency was 1.6% at an output beam power of 240W. With an intracavity polarizer and with the cavity optics adjusted to restrict the output beam divergence to 5 mrad, a polarized output beam of 140W was obtained with 14kW lamp input power. The maximum stable TEM (sub infinity) beam power output was 15W. In normal pulse operation (140 microsec pulse length), 5.3 J/pulse output at 10 pps and 15 mm milliradians was demonstrated with 1% efficiency.
