Stark cell noise reduction of a CO2 laser beam
Abstract
A technique is demonstrated for reducing the rapid intensity fluctuations in the beam of a single-frequency, polarized CO2 laser tuned to the P(20) transition at 10.6 microns. The method uses a Stark-tunable absorption line in NH2D to compensate for the fluctuations of the laser output. Substantial reductions in laser beam intensity noise have been obtained. The method may be applied to other lines of the CO2 laser and to other types of lasers.
