Performance of a prototype module of a 300-watt flashlamp-pumped dye laser
Recent performance measurements on a prototype module of a multi-beam, flashlamp-pumped dye-laser system are discussed. Measurements of the total output energy of the dye laser and its distribution in the far field are presented for operation at a 5-Hz repetition rate. The implementation of a real-time dye-regeneration system and the choice of an optimum dye solvent are addressed. A large, multi-beam, flashlamp-pumped dye-laser system is being constructed for a field experiment. Performance measurements made on a prototype module of this laser system are presented. A test bed was assembled at the Laboratory that has the capability of supporting two of these dye-laser modules, and implements many of the unique features of the final system, such as on-line laser-performance diagnostics and the capability to overcome the detrimental effects of finite dye lifetime during operation of the system. The laser system test bed has fluid control, cooling, and electrical support for two separate laser beams working at full output power. There is also a provision for operating three laser beams at a reduced power level. This system has yielded valuable data on both laser performance and engineering aspects. Among the innovative features of the dye-laser system is the ability to run the lasers for extended periods of time without suffering the deleterious effects of dye degradation. Instruments monitor the level of photodegradation products in the dye process stream and direct a fraction of the dye into a carbon absorber, where the degradation products are removed.
