Abstract

Solid-state dye-doped materials offer obvious advantages over traditional liquid solutions as active medium of tunable lasers [1]. Although these materials have been under extensive investigation for a long time, considerable improvement in their lasing properties has not been achieved until recently [2]. The low stability of the dyes impregnated into the solid-state host matrices has been a disadvantage which has restricted the commercial promotion of polymer materials as the active medium in tunable lasers. Also, a complete picture of the processes responsible for dye destruction in solid solutions is still to be presented.
