Abstract

The oscillator-amplifier of RB (Rodamin B) dye laser has been setup by using the second harmonic generation of Nd:YAG laser (15ns pulse duration, 35mJ maximum output energy) as a pump. The output energy of oscillator and amplifier were measured separately and the variation of amplifier dye concentration on the output energy was investigated. The above experiments were repeated for R6G (Rodamin 6G) and the results were compared with RB. By putting a convex lens in a proper place inside the RB dye oscillator resonator, the output power was increased by approximately 39%. Experimental results show good agreement with theoretical investigation.
