Abstract

By considering the Guassian distribution of the pump beam and the thermal effect in the gain medium, the coupled rate equations of a LD pumped passively Q switched Nd∶YVO4 laser at 1.06μm with GaAs are given. The theoretical average output power , pulse width,pulse repetition of the laser are obtained by the numerical solution of the rate equations. The experimental results agree with the numerical solutions of the coupled rate equations.
