The monoclinic vanadate Nd:LaVO(4) crystal was characterized, including the first investigation of thermal properties and anisotropic laser performance to our knowledge. The thermal properties behave anisotropically with the highest thermal conductivity of 3.27 W/m/K along the c* direction. With a laser diode as the pump source, the efficient continuous-wave (cw) and passively Q-switched monoclinic Nd:LaVO(4) crystal lasers were realized, which resulted in the nearly isotropic maximum output power and laser wavelength. The maximum cw output power is 3.56 W with a slope efficiency of 41.4%, and the passively Q-switched pulse width is 10.9 ns with pulse energy of 38.3 μJ. Based on the laser results, the thermal shock parameter anisotropy is calculated to be 1:1.28. The results show that, in contrast to other vanadate crystals, Nd:LaVO(4) is a novel laser material with low symmetry.
镧钒酸盐（Nd:LaVO₄）晶体进行了表征，据我们所知，这是首次对其热性能和各向异性激光性能进行研究。热性能表现出各向异性，沿c*方向具有3.27 W/m/K的最高热导率。以激光二极管作为泵浦源，实现了高效的连续波（cw）和被动调Q单斜钕：镧钒酸盐（Nd:LaVO₄）晶体激光器，其输出功率和激光波长接近各向同性。最大连续波输出功率为3.56 W，斜率效率为41.4%，被动调Q脉冲宽度为10.9 ns，脉冲能量为38.3 μJ。基于激光实验结果，计算出热冲击参数各向异性为1:1.28。结果表明，与其他钒酸盐晶体相比，钕：镧钒酸盐（Nd:LaVO₄）是一种具有低对称性的新型激光材料。
