Abstract
Frequency stabilized solid state lasers related to the gravitaional wave detection are reviewed. In order to detect gravitaional waves from super novae or a coallescence binary stars, the sensitivity should be higher than 10-19 to 10-22. A large interferometer is a possible solution if we can develop a stable light source, mode cleaner optics, free-mass optical cavity, anti-vibration systems operating at their quantum or theoretical limits. We measured the FM-noise at the shot noise limit by means of LD-pumped YAG lasers. The tracking capability was examined by the beatnote spectrum of 193 mHz directly. The measured spectrum and Allan root variance showed that the beat line width is determined by the thermal drift of reference cavities in two-laser and two-cavity mode. We report the present status of technological develop-ment of ultra-stabilized lasers, ultra-high quality optics, and high power lasers for gravitational wave measurements.
