Abstract

In this paper, we report for the first time, control of the output-pulse-energy characteristics of a CW pumped, high repetition rate, passively Q-switched Nd:YVO4/Cr:YAG microchip laser by using the large reduction of the stimulated emission cross-section of the Nd:YVO4 crystal on increasing its temperature. We demonstrate our results by showing the very significant improvement in the supercontinuum generated in a photonic crystal fiber by the microchip laser output, when the Nd:YVO4 crystal temperature is increased from 25℃ to 55℃. The results will be very useful for achieving very compact, high repetition rate and high pulse energy lasers for various applications.
