“…The quasi-phase matching optical parametric oscillator (QPM-OPO) based on the superlattice material is an effective technique to obtain near and mid-infrared bands of 1.5-5 μm [1][2][3][4] . The typical wavelength laser in these bands has an irreplaceably important role in the fields of precision measurement, remote sensing detection, and optoelectronic countermeasures.…”

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%.
