 note = {Space solar power station needs an energetic and efficient laser as the energy transfer device from a broadband solar light to a coherent laser light. The concept of active-mirror amplifier with transparent Nd/Cr:YAG (Yttrium Aluminum Garnet) ceramics is proposed under consideration how to convert a wide spectrum of sun light to a monochromatic laser light. New ceramic material pumped by an arc-metal-halide lamp has been implemented experimentally as a fundamental prototype for the space solar power station. CW (Continuous Wave) laser light generated in a LD (Laser Dye)-pumped 1,064-nm Nd:YAG rod laser oscillator was amplified so that a spatial mode of laser output has been improved to Gaussian mode. The saturated amplification of output laser power was observed at around 40 W/sq cm in output power density when the diameter of input laser profile was 18 mm. The maximum output laser power obtained was up to 180 W (about 60 W/sq cm) with keeping spatial beam quality when Nd:YAG ceramics doped Cr ions density of 3 percent was used., 資料番号: AA0063965018},
