Efficient distributed feedback solid state dye laser with a dynamic grating

We present the first operation of a distributed feedback solid state dye la ser with a dynamic, pump-induced grating. Broadly tunable, narrow band oper ation in the region of 616 nm (604-649 nm) has been demonstrated with peryl ene red laser dye doped in poly(methyl methacrylate) (PMMA), when pumped wi th a frequency doubled Nd:YAG laser. Conversion efficiencies of 20%, corres ponding to 35% optical-to-optical efficiency, have been measured. The laser bandwidth was between 0.01 and 0.04 nm, and smooth tuning over more than 2 00 GHz has been demonstrated.
