Abstract

The simulation and optimization of Q-switched Nd:GdVO₄ quasi-three-level 912 nm laser under Gaussian pump beam distribution is conducted with considering the spatial distribution of intracavity photon density. The steady state rate equation for the population accumulation involves the energy transfer upconversion effects while the rate equations with ground state absorption are used to describe the pulse generation process. The influence of the energy transfer upconversion and ground state absorption effects on the output characters of pulsed 912 nm laser are estimated under different pump conditions. Based on the model, the optimized parameters of Q-switched Nd:GdVO₄ quasi-three-level 912 nm laser are obtained. This simulation method can be used to analyze and optimize the Q-switched quasi-three-level lasers under Gaussian beam pump.
