Abstract

For the light source of the gravitational wave detector, the injection-locked Nd:YAG laser has been developed in which high power with high frequency stability is required. The frequency of the injection-locked laser is stabilized to the high- finesse Fabry-Perot optical resonator to suppress frequency noise down to 2 X 10^-2 Hz/(root)Hz at 1 kHz. To improve the long term frequency-stability, the frequency of the injection-locked laser is locked to both the high-finesse Fabry-Perot cavity and to the hyperfine components of the rovibrational transition of ¹²⁷I₂ simultaneously by the offset-locking technique. The frequency drift of the high- finesse Fabry-Perot cavity is estimated which is measured from the frequency difference between Fabry-Perot resonate frequency and iodine transition frequency.
