Paper Abstract

A CO2 laser for an optically pumped CH OHlaser is stabilized on the center of the CH3OH absorption line y using a photo-acoustic spectroscopy. The frequency stability is measured by referring to a CO2 laser which is stabilized by Freed-Javan method. The stability of the pump laser is obtained to be Jy(t) = 3.0 x 10-9 x t-1 /2 ( is , 1:c100s ) in the terms of the square root of Allan variance. The offset frequency between the CO2 laser line center and the CH3OH absorption line center is also obtained from the beat frequency to be 24.8± 0.1 MHz.
