Gain studies of coumarin 307 dye doped polymer laser

Solid state dye doped polymer is an attractive alternative to the conventional liquid dye solution. In this paper the laser characteristics of coumarin 307 (C307) doped polymethyl methacrylate rods modified with dioxane are studied under nitrogen laser excitation in a transverse pumping configuration and the variation of gain of the dye in solid medium for different pumping powers is studied. The photobleaching of dye doped polymer rod is also studied.
