Abstract
In order to develop a high-efficiency pulsed dye laser, laser efficiencies of various dyes were measured at three different pumping wavelengths of the Cu vapor laser (511 nm and 578 nm) and the frequency-doubled Nd:YAG laser (532 nm) in the same condition. A simulation model for Rhodamine 6G (R-6G) dye laser was also developed to analyze the effect of excitation wavelengths. Some Rhodamine dyes show higher efficiency than those of R-6G in simultaneous two-wavelength pumping by a Cu vapor laser. A dye mixture of Cresyl Violet 670 and Rhodamine 640 was as efficient as R-6G in the 653-660nm region.
