Abstract

Random lasing in a nanocrystaline Nd<sup>3+</sup>:YVO<sub>4</sub> powder is demonstrated for the first time. Lasing action is demonstrated by a method that analyzes the decay kinetics after long-pulse excitation. This method permits to measure the fractional contribution of each component produced in the random laser as a function of the pump intensity, namely spontaneous and stimulated emission as well as upconversion.
