报告题目：Introduction of Solar-pumped Laser and Laser Propulsion

内容简介：We developed solar-pumped laser with Fresnel lens and concentrators. 120W of laser output and collection efficiency of 30W/m^2 was realized. In this talk, we introduce development of each elements to realize the solar-pumped laser. Furthermore, we developed new technology so called "Water Cannon" to realize large coupling coefficient for laser propulsion. Several thousands of coupling coefficients are realized using water as transparent material. In this talk, we introduce how to get large coupling coefficient using water and show you several demonstrations.
