摘要：

Presented here are experimental results for a high-energy solid-state dye laser with different laser resistant polymer active elements impregnated with pyrromethene and xanthene dyes. It was pumped by a unique frequency doubled Medlite(TM) TV Nd: YAG laser with pulse energies up to 660mJ, pulse width 5-7ns and pulse repetition rates up to 10Hz developed by Continuum Biomedical. A dye laser output energy greater than or equal to 525mJ in broad band operation mode and slope efficiency over 80% were demonstrated at pump fluences up to 3J/cm(2). No laser-induced damage of the modified polymer elements was detected up to these levels of fluence. A stable output for more than 150,000 pulses at 585nm, for a fixed area of the polymer element, at a pump fluence of 1.3J/cm(2) has been achieved.
