Abstract : The objective of this program is to develop a miniaturized dye laser suitable for a variety of applications, particularly in an underwater environment. The following tasks have been performed: Re-evaluate alternative pumps cavity configurations; Perform preliminary tests of promising new coumarin dyes; Investigate the use of increased flashlamp input energy; Evaluate the use of reduced arc length and of arc image defocussing to reduce pulse amplitude fluctuations; Redesign the laser resonator for improved efficiency; Investigate the effects of dye filtering and increased dye flow rates; Demonstrate laser operation with 100 watt usable peak power output, at a pulse repetition rate of at least 200 pps, for a non-stop operating period in excess of 20 seconds. This interim report presents a summary of the results of these investigations, followed by a brief outline of plans for continuing work in the next reporting period.
