Abstract
A procedure of numerical modeling of an optical parametric oscillator in the cavity–dumping mode has been developed. For the optical parametric oscillator based on a KTP crystal the dependences of the temporary profile and energy of the signal pulses (λs = 1.57 μm) on the time of switching and depth of modulation of the reflection factor of the output mirror at prescribed length and energy of the Gaussian pulse of pumping an Nd:YAG laser (λp = 1.064 μm) are calculated. An optimum mode of controlling extraction of radiation that ensures the maximum efficiency of conversion due to reduction of nonlinear losses has been found. The possibility of forming gigantic pulses by the optical parametric oscillator with the peak intensity greatly exceeding the intensity of pumping is shown.
