| Abstract: | The 1064nm acousto-optically Q-switched diode-end-pumped Nd:YAG laser which works as the pump source for the optical parametric oscillator is investigated in this paper.Proceeding from the specific properties of Nd:YAG laser,the characteristics of the LD end-pumped Q-switched Nd:YAG laser are explored.Through the equivalenting,analyzing and calculating of the resonator configuration,the conditions of stable resonator and the curves of radii of beam waist along with the change of length of cavity are worked out.In addition,the form of pulse after numerically calculating the Q-switched rate equations is obtained and the influence of the form and pulse width on signal are analyzed.All these findings in the paper bear certain guiding significance to the production of the high-quality optical parametric oscillation with broad tuning and high conversion efficiency. |
