摘要
With a laser diode as the pump source, a passive Q switching of an intracavity frequency-doubling Nd: GdVO4 green laser with periodically poled KTP has been realized with a Cr4+:YAG saturable absorber. The dependences of the average output power, pulse width, pulse repetition rate, pulse energy, and peak power on incident pump power at different small-signal transmissions of Cr4+: YAG are measured. The rate equations considering the Gaussian spatial distribution of the intracavity photon density and the effects of the amplified spontaneous emission (ASE) are presented to simulate the Q-switching process of this laser, and the numerical solutions are in agreement with the experimental results. We have further discussed the influences of the ASE parameter 6 on the laser performance.
