ResumoThe ne laser dye, perylene orange, doped into polycom glass (sol-gel glass-poly(methyl methacrylate) composite) has been developed into a tunable gain material ith high performance.,A sample polished to 0.02μm smoothness and λ/5 flatness, over the central region, as excited in an optical cavity with a second harmonic Q-switched Nd-doped yttrium aluminium garnet laser as a pump source. The solid-state dye laser had a threshold of 53 μJ, a slope efficiency of 72%, and a normalized photostability of 50 GJ mol -1 The laser damage thresholds of various host materials were obtained and the damage threshold of polycom glass was found to be 26 J cm -2 . The beam profile of a He-Ne laser transmitted through samples of host material showed that the optical homogeneity of polycom glass is approaching that of pure polymers.
