Abstract

A simple method for single-frequency operation and stabilization of a low power He−Ne laser has been described and used. With a proper resonator length very weak sideband modes on each side of the strong mode produce a feedback signal to a piezoelectric pusher which controls the resonator length. The long-term frequency stability was estimated to be about ±10 MHz.
