Abstract

Solid state tunable lasers were prepared by the sol-gel method either in bulk form or as thin wave guiding films deposited on glass or quartz. The active material were perylimide dyes providing laser emission between 550-630 nm. The lasers obtained were extremely photostable surviving more than 1 million pulses of the second harmonic Nd:YAG laser, providing 50 mJ/pulse. Slope efficiencies of more than 20% can be obtained when longitudinal pumping is used at appropriate geometries. New composite materials based on polycondensation of alkoxysilanes with organically modified silanes are proposed as the laser host for leaking wave guides and titanium oxide modified films for wave guide lasers.
