Abstract
Using the ABCD matrix theory that takes into account the thermal lens effect of the gain medium and rate equations that consider the Gaussian spatial distributions of the intracavity photon density and pump beam, the pulse duration of a passively Q-switched laser is optimized by choosing the appropriate oscillating beam radius on the Q-switch wafer and pump beam radius in the gain medium, which provides a simple way to optimize the pulse duration. By changing the positions of the GaAs in the cavity or the pump beam focal plane in the gain medium in a diode-pumped passively Q-switched Nd:YVO4 laser with a GaAs saturable absorber, the optimization of pulse duration is easily realized, which is in good agreement with the theoretical calculations.
