Abstract
Recently, modulation of the output from a chemical oxygen iodine laser (COIL) has been demonstrated by applying a pulsed magnetic field directly to the laser cavity. A peak-to- average power enhancement of 3.2 was obtained. The rate of change of the magnetic field in these experiments, however, was relatively slow, 0.5 gauss/microsecond(s) . In this article, we report the demonstration of a fast field switching technique (325 gauss/microsecond(s) ), in which switching occurs faster than the laser mode can build up. With this technique, we have achieved a peak- to-average power enhancement of 12.7 and achieved true gain-switched operation.
