Permitted Parametric of Optical Parametric Oscillator Based on PPRTA

The relative gain intensity and corresponding permitted parametric of optical parametric oscillator based on periodically poled RbTiOAsO4 (PPRTA) have been analyzed and simulated. The permitted grating period of PPRTA was compared with those of periodically poled lithium niobate (PPLN) and periodically poled potassium titanyl phosphate (PPKTP).
