Development of Solar-Pumped Solid-State Laser

Abstract

The solar pumped solid state laser is the system which changes sunlight into a laser. We are developing a solar pumped solid state laser for Space Solar Power Systems (SSPS) that require over 20 % effi ciency and a high-power. We designed a solar pumped laser system with over 20 % laser effi ciency in 2007. In this paper, fi rst, we describe the previous overseas solar laser development status. Next, we describe the previous domestic solar laser development status. Laser effi ciency using the sunlight is equal to or less than 1 % at domestically and abroad. Finally, we describe our solar pumped laser development.
