Interferometric gravitational wave detector TAMA-300 and the frequency-stabilized laser with high-finesse optical resonator

The laser interferometric gravitational wave detection by means of a long-baseline laser interferometer has been promoted in Japan. To obtain higher sensitivity for detect gravitational wave, high-quality mirrors and the high-power laser with high frequency-stability are important. In this paper our improvement of high-quality mirrors through development of high-precision measurement and the frequency stabilization of the injection-locked laser was reported.
