Abstract

Summary form only given. We report, to our knowledge, the first tunable solid state DFB laser using a dynamic, pump-induced grating. We used Perylene Red dye-doped polymer DFB gain media, fabricated by dissolving Perylene Red laser dye in methyl methacrylate monomer prior to polymerisation. The dye-doped poly(methyl methacrylate) (PMMA) polymers were cut into trapezoidal slabs with the output faces slanted at /spl sim/10/spl deg/ to eliminate parasitic lasing due to Fresnel reflections from these faces. The pump laser was a second harmonic single mode Q-switched Nd:YAG laser.
