We report on telecom laser frequency stabilization to narrow iodine hyperfine line in the green range of the optical domain, after a frequency tripling process using two nonlinear PPLN crystals. We have generated up to 300 mW optical power in the green (P-3 omega), from 800 mW of infrared power (P-omega). This result corresponds to an optical conversion efficiency eta = P-3 omega/P-omega similar to 36 %. To our knowledge, this is the best value ever demonstrated for a CW frequency tripling process. We have used a narrow linewidth iodine hyperfine line (component a(1) of the I-127(2) R 35 (44-0) line) to stabilize the IR laser yielding to frequency stability of 4.8x10(-14)tau(-1/2) with a minimum value of 6x10(-15) reached after 50 s of integration time. The whole optical setup is very compact and mostly optically fibered. This approach opens the way for efficient and elegant architecture development for space applications as one of several potential uses.
