Abstract

Theoretical calculations of the output characteristics about the periodically poled crystals-based intra-cavity second harmonic generation of the resonant wave in the singly resonant optical parametric oscillator (IC-SHG-SRO) are presented. Under the collimated Gaussian beam approximation, simple models are set up and the outputs of the IC-SHGSRO are shown theoretically. The calculations based on the experimental parameters are in good agreement with the experimental results. The output characteristics of the 532 nm green laser pumped IC-SHG-SRO resonating at 795 nm and the 1064 nm infrared laser pumped IC-SHG-SRO resonating at 1590 nm are predicted. The calculations demonstrate that there exists the optimum length of SHG crystal to obtain the maximum SH output for the given experimental conditions. These calculations and the models provide guidelines for designing and optimizing the continuous-wave ICSHG- SRO.
