提出了一种新型的正交线偏振的Nd：YVO4激光器。将两块α切割生长的YVO_4/Nd：YVO_4复合晶体置于两晶体c轴垂直的谐振腔中。研究了正交偏振激光器的偏振特性和功率特性。获得了26.2W的正交线偏振激光器。两正交偏振激光器之间的功率比随偏振模耦合产生的泵浦功率而变化。此外，还观察到了垂直偏振激光器的纵模竞争和相应的可变光拍。我们还对晶体进行了c轴平行调整，获得了40.7W的线偏振TEM00激光器，其光束质量因子分别为Mx2=1.37和My2=1.25。
We presented a novel orthogonally linearly polarized Nd:YVO4 laser. Two pieces of α-cut grown-together composite YVO4/Nd:YVO4 crystals were placed in the resonant cavity with the c-axis of the two crystals orthogonally. The polarization and power performance of the orthogonally polarized laser were investigated. A 26.2-W orthogonally linearly polarized laser was obtained. The power ratio between the two orthogonally polarized lasers was varied with the pump power caused by the polarized mode coupling. The longitudinal modes competition and the corresponding variable optical beats were also observed from the orthogonally polarized laser. We also adjusted the crystals with their c-axis parallele to each other, and a 40.7-W linearly polarized TEM00 laser was obtained, and the beam quality factors were Mx2 = 1.37 and My2 = 1.25.
