“…The high-frequency wave is called "pump," the higher low-frequency wave is called "signal," and the other low-frequency wave is the "idler." In an OPO process, when a strong pump beam is irradiated into the nonlinear crystal in the resonator, if the gain exceeds the loss, the signal and idler waves (parametric waves) are generated beyond the noise and amplified [5,6]. When the power of the parametric waves reaches a certain value, the energy flows from the parametric waves to the pump wave, resulting in a decrease in the gain of the parametric wave.…”

In this paper, a calculation model is proposed for the optical parametric oscillation (OPO) process considering the crystal thermal effects. Based on existing models, we combine a set of three-wave coupled equations with the Sellmeier equation. In order to optimize the calculation of the nonlinear process, a temperature variable t is introduced to describe the heat generated by the laser crystal during operation. The waveforms under different pump powers are analyzed. The effects of the reflectivity of the output mirror on the OPO threshold and inverse conversion are investigated. In addition, the optimal reflectivity under different pump powers can be estimated. Based on the simulation results, experiments are also performed in the near-infrared 1.57 µm band and mid-infrared 3.15 µm band. The experimental results are compared with the results of this model and a model that does not consider crystal thermal effects. The experimental results are consistent with the improved theoretical results, affirming that the proposed theoretical model can simulate the energy conversion process of OPO. This provides a theoretical basis for optimizing the parameters of the OPO output mirror and improving the efficiency of the parametric wave conversion.

The back conversion of optical parametric oscillator seriously restricts its application in spectral analysis, optical holography, lidar and so on. The optical parametric amplifier output energy is simulated theoretically, and it is confirmed that the back conversion can be compensated by reducing the input energy of parametric light. An optical parametric oscillator with electro-optically polarization mode converter in the resonant is proposed to change the polarization state of the parametric light and adjust the proportion involved in the oscillation. The polarization mode conversion of MgO:PPLN crystal is analyzed theoretically. The experiment of energy regulatory structure is carried out. When the applied voltage of electro-optically polarization mode converter is 157 V/mm, the maximum output power of 1.47 μm and 3.84 μm are 4.4 W and 3.7 W, with a ratio of 1.2. It is confirmed that such structure can suppress back conversion and adjust the output ratio.

In this study, the heat distributions of MgO∶PPLN crystals under different incident pump optical radii are simulated and analyzed. Considering the temperature rise phenomenon near the central axis of the crystal during operation, the crystal heating parameter t is added to optimize the crystal temperature tuning curve. The inverse conversion phenomenon of MgO∶ PPLN optical parametric oscillation (OPO) is experimentally analyzed. Furthermore, the relationship between the parametric light reflectance of the cavity mirror and the optimal pump superthreshold multiple is investigated, and the effect of crystal length on the OPO conversion efficiency is analyzed. By optimizing the experiments, the continuous change range of the signal light wavelength in the temperature range of 30 -190 °C is measured to be 1568. 9 -1659. 8 nm. At a pump power of 1. 12 W, repetition frequency of 15 kHz, and temperature of 90 °C, the obtained nearinfrared laser output is 1595 nm with a maximum average power of 110 mW.
