Pulse Amplification Characteristics of a Laser Amplifier in a Magnetic Field.
Abstract
This report describes and gives the results of a numerical modeling of the energy amplification characteristics of a pulsed iodine gas laser power amplifier in an applied inhomogeneous magnetic field. The purpose of the applied field is to increase the feedback limited energy storage capability of the laser medium. The lasing transition is taken to have a normal Zeeman doublet structure. Curves are presented to illustrate the parametric dependence of the energy amplification and extraction efficiency on small-signal amplification, peak field strength, and input pulse characteristics. It is shown that a 10-fold increase in output energy per pulse can be anticipated by using this technique.
