Magnetic Enhancement of the Energy Storage Capability in a Laser Power Amplifier.

Abstract

This is the first of three reports describing an investigation of a particular technique for increasing the energy storage capability of a laser power amplifier. The problem area addressed is the energy storage limit which results from the optical gain threshold for spontaneous oscillation of the amplifier. The goal is to assess the potential of the use of a spatially inhomogeneous magnetic field to lower the peak small-signal amplification by spatially varying the frequencies of the Zeeman components of the lasing transition. This report describes and gives the results of a theoretical study of the technique applied to the photo-disassociative Iodine laser system. The hyperfine structure of the transition is included. The results show a significant increase in energy storage capability can be achieved with reasonable peak fields, depending on the line width of the individual Zeeman components.
