SINGLE-FREQUENCY LIGHT FROM AN ARGON FM LASER

Abstract

An experiment is described in which 350 mW of single‐frequency light at 5145 Å was obtained using an argon FM laser with an external LiNbO₃ modulator. Data on overall conversion efficiency from multifrequency to single‐frequency light are presented. Also discussed is the reduction in distortion with increasing optical power. Total sideband content was less than 0.125% of the maximum optical power, corresponding to an ac ripple of 3.5% rms.
