Design,Construction,and Operation of an Experimental System for Study of Laser Energy Enhancement by Magnetic Fields.

摘要

An experimental system has been designed and constructed for the study of iodine laser energy enhancement. The system is an oscillator-amplifier combination in which the energy storage capability of the amplifier is increased by the application of an inhomogeneous magnetic field which provides a spatial variation in the frequency profile of the induced emission coefficient. Photo-dissociative flux is provided by high energy linear flashlamps. The coaxial lamp current path produces no net force on the lamp structure;therefore,even with high lamp currents (up to 20kA) and high magnetic fields (up to 100kG),satisfactory lamp operation can be achieved. This report outlines the overall design and operation of the experimental apparatus,including the electrical system,vacuum/gas handling system,power amplifier/master oscillator system,and optical system. A discussion of the flashlamps,including results of the initial flashlamp study and flux measurement,is included in the section on the electrical system.
