Computer-controlled laser amplitude modulation

Abstract

Laser amplitude modulation having specific quadratic waveforms has been demonstrated. Reproduction of the desired waveforms is accomplished within 0.5 %. The waveforms are computer generated and applied as discrete steps to a laser amplitude modulator. It is necessary to quiet the laser amplitude noise to within 0.1 % and to compensate for the Inherent nonlinearities of the modulation process. Although the functions here are quadratic, other waveforms, computer generated, would be applicable as well.
