抄録（英）
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 recent rapid progresses of the laser technologies make possible to convert from solar power to laser efficiently. The concept of active-mirror amplifier with transparent Nd/Cr:YAG 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. We introduce the topics for the first lasing of solar-pumped laser and the status of the developing solar-pumped laser in the over sea and the domestic.
