Paper Abstract

The performance of Q-switch DPL output giant pulse can be optimized by utilized the site of maximum diffraction efficiency of acousto-optic Q-switch. Based on the model of spot acoustic source, spatial distribution of ultrasound field in acousto-optic crystal is studied by numerical calculation with considering the factor of acoustic attenuation. Distribution of diffraction efficiency in acousto-optic crystal is obtained by analysis it. So the site of maximum diffraction efficiency is found, and the same outcome is obtained in experiment. The channel selection technology is put forward based on the study on spatial distribution of diffraction efficiency in acousto-optic crystal that is benefit to obtain optimal parameters (which include the peak power, pulse width, etc) in DPL.
