“…The optical parametric oscillator based on periodically poled LiNbO 3 crystals is an effective method to obtain coherent radiations in the eye-safe range of 1.5 µm and midinfrared range of 3-5 μm, which has various applications in spectral analysis and remote sensing [1][2][3][4]. Optical parametric oscillation (OPO) uses the second-order nonlinear threewave frequency mixing progress to realize the frequency conversion.…”

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.

“…Compared with the traditional superlattice material MgO-doped periodically poled LiNbO 3 (PPLN), the Nd:MgO:PPLN is formed by further polarization treatment with Nd 3 -doped MgO:LiNbO 3 as the substrate. This crystal can complete the two processes of fundamental frequency optical gain and optical parametric frequency conversion in this single medium, which is called optical parametric oscillation self-frequency conversion [5][6][7][8] . This feature provides a new way to realize the small-scale integration of such lasers, which has been of wide concern and studied in recent years.…”

A continuous-wave (CW) π-polarized 1084 nm laser based on Nd:MgO:LiNbO 3 under 888 nm thermally boosted pumping is reported. According to the absorption spectrum and energy level structure of Nd:MgO:LiNbO 3 , the 888 nm laser diode (LD) is used for thermally boosted pumping. This pumping method eliminates the quantum defect caused by the nonradiative transition in Nd:MgO:LiNbO 3 under the traditional 813 nm pumping and effectively improves the serious thermal effect of the crystal. The unmatched polarized 1093 nm laser is completely suppressed, and the π-polarized laser output of 1084 nm in the whole pump range is realized by the 888 nm thermally boosted pumping. In the present work, we achieved the CW π-polarized 1084 nm laser with a maximum output power of 7.53 W and a slope efficiency of about 46.1%.
