ABSTRACT
We report an experimental investigation on the thermal effects in a Nd[sup 3+]:Y[sub 3]Al[sub 5]O[sub 12] nanocrystalline-powder random laser with a one-mirror structure by quasi-continuous-wave laser diode pumping. Extremely low thermal conductivity in powder and significant temperature dependence of the narrow emission spectrum of Nd[sup 3+]:Y[sub 3]Al[sub 5]O[sub 12] leads to a laser line redshift and gain reduction with a higher heat deposit. Mode drifting induced by the temperature dependence of the refractive index is also discussed. © 2004 American Institute of Physics.
