A comparison between the fluorescence spectra of the Nd-doped vanadate crystals (Nd:YVO4, Nd:GdVO4, Nd:LuVO4) for the 4F3/2 → 4I11/2 transition is studied. We numerically analyze the condition of gain-to-loss balance via an uncoated intracavity etalon to achieve the dual-wavelength operation. We further experimentally demonstrate the orthogonally polarized dual-wavelength laser with a single Nd:LuVO4 crystal. The simultaneous dual-wavelength Nd:LuVO4 laser at 1085.7 nm in σ polarization and 1088.5 nm in π polarization is realized. At an incident pump power of 12 W, the average output power obtained at 1085.7 nm and 1088.5 nm is 0.4 W and 1.7 W, respectively.
研究了掺钕钒酸盐晶体（Nd:YVO4、Nd:GdVO4、Nd:LuVO4）在4F3/2→4I11/2跃迁下的荧光光谱之间的比较。我们通过未镀膜的腔内标准具对增益与损耗平衡的条件进行了数值分析，以实现双波长运转。我们进一步通过实验展示了利用单块Nd:LuVO4晶体实现的正交偏振双波长激光器。实现了在σ偏振下波长为1085.7 nm和在π偏振下波长为1088.5 nm的同时双波长Nd:LuVO4激光器。在12 W的入射泵浦功率下，在1085.7 nm和1088.5 nm处获得的平均输出功率分别为0.4 W和1.7 W。
