A Variable Gain Laser Amplifier at 3.39 mgr;

摘要

A variable gain laser amplifier has been tested that appears capable of operating over a wide range of gain values. The gain is controlled by placing the amplifier in a Fabryhyphen;Perot cavity and allowing it to oscillate. Small changes in amplifier cavity length produce large variations in the amplifier gain. Measured gain variations of 20 : 1 have been observed.
