In this paper, we report the result of the field experiment of laser power transmission over 500 m using different laser systems, i.e. CO2, YAG, etc. The efficiency of energy transmission for long time period under various meteorological conditions was measured. We have observed large and long time scale fluctuation of beam pointing. It is found that the position of laser beam at the receiving site is correlated with the temperature difference between laser path height and ground. The laser to electricity conversion experiment has been performed using GaAs, c-Si, tandem-type a-Si, and CuInSe2 (CIS) solar cells. Finally, we briefly introduce the proposal on the space experiment of laser power transmission at Japanese Experiment Module (JEM) on the international space station.
