Abstract
A polymeric high gain scattering medium based on IR-26 laser dye mixed with sub-micron alumina scatterers is described. Optical pumping at 1.06 micrometer with a Q-switched Nd:YAG laser results in isotropic, narrowband emission peaking at 1.18 micrometer. Alternative high gain, narrowband visible stimulated emitters utilizing a high density of microprism retroreflectors for optical feedback are also described. Optical pumping at 532 nm with the Q-switched output of a frequency-doubled Nd:YAG laser results in narrow linewidth, Stokes-shifted laser emission near 600 nm.
