Nowadays, wide range of space missions including space interferometry laser, fundamental physic tests, ranging measurement, distance changes between space aircraft and optical communication with each other or with ground reference, etc … require powerful lasers in a compact set-up configuration with highly intrinsic frequency stability. The couple “frequency doubled Nd:YAG laser and iodine molecular transition” in the green range of the optical domain, is one of the most promising candidate with superior frequency stability for various applications. LISA (Laser Interferometer Space Antenna), DECIGO (DECI-Hertz Interferometer Gravitational wave Observatory), STAR (Space Time Asymmetry Research), Post-GRACE (Gravity Recovery and Climate Experiment) are few examples of space missions based on ultra stable laser use. We report on our ongoing development of Nd:YAG stabilized laser using an original and reliable experimental configuration with expected frequency stability in the 10-15 range over thousands of seconds of integration time.
