Abstract

Abstract Solid state dye doped polymer is an attractive alternative to the conventional liquid dye solution. In this paper, the laser characteristics of Rhodamine 6G (Rh6G) doped polymethyl methacrylate (PMMA) rods, modified with ethyl alcohol (EtOH), are examined by nitrogen laser, and second harmonic Nd : YAG laser excitations in a transverse pumping configuration and the variation of small signal gain of the dye in solid medium for different pump powers are studied. The photobleaching of dye doped polymer rod is also studied.
