摘要

By using Nd: YVO4 as the gain medium and the Raman medium simultaneously, the actively Q-switched operation of the self-Raman Nd: YVO4 laser at 1176 nm was realized. The output characteristics including the average power, pulse energy and pulse width versus the incident pump power and pulse repetition rate were investigated. At a pulse repetition rate of 20 kHz an average power up to 0.57W was obtained with the incident pump power of 10.2W, corresponding to a conversion efficiency of 5.6% with respect to the diode laser input power. Meanwhile, an analysis of the self-Raman Nd: YVO4 laser was carried out by using the rate equations. The obtained theoretical results were in agreement with the experimental results on the whole.
