Active Filtering for Optical Pumps.
Abstract
Eleven fluorescing organic dyes were tested for their ability to alter the spectrum of a flashlamp in such a way as to increase the light intensity in one or more of neodymium laser pump bands. The dyes were tested in a Nd:YAG laser system at flashlamp pulse energies from 3J to 15J. A few of the dyes gave a marked improvement in the output energy and slope efficiency of the pulsed Nd:YAG laser. Rhodamine 6G was identified as the best dye, giving better than 50% improvement in the laser output for 15J, 140 microsecond flashlamp pulses such as: Bleaching of the Rhodamine 6G dye solution under flashlamp illumination requires the volume of the circulating dye to be approximately 2 liters for a half life of 1 million-5 joule pulses.
