Frequency Stabilization of Frequency-doubled Nd:YAG Lasers at 532 nm

By G. GALZERANO, E. BAVA, BISI M, F. BERTINETTO and C. SVELTO

Abstract

Frequency-doubled Nd : YAG lasers have been frequency stabilized against the hyperfine structure components of 127I2 by means of the sub-Doppler frequency modulation technique. A frequency stability of 3e-13/sqrt(tau) has been obtained for integration times between 1 ms < tau < 100 s with an estimated reproducibility of about 1 kHz (2E-12). The hyperfine spectroscopy of the rovibrational line P(54)32-0 has been performed and the iodine hyperfine constants have been calculated. The pressure shifts of the hyperfine components a1, a2, a10 and a15 have been measured
