Abstract
We developed three types of frequency stabilized semiconductor lasers (LD) source or optical synthesizers using 12C2H2 or H13C14N absorption lines. This paper reports on the three methods below: (1) A frequency stabilized LD source controlled by sinusoidal LD current modulation reduced to lowest possible values. The maximum frequency deviation was +/- 5 MHz. And a frequency stability of 9 X 10-10 (DOT) (tau) -1/2 (0.1 s 12C2H2 absorption line and a frequency stability of less than 1.0 X 10-9 (10 s 13C14N absorption line were obtained from the beat method. (2) An optical synthesizer using two LDs and a newly developed frequency control method. The frequency synthesized range was +/- 2 GHz from the absorption frequency. A short-term frequency stability of about 2 X 10-9 (DOT) (tau) -1/2 (0.1 s -10 (10 s
