This study investigated the laser performance of a Nd:GdTaO₄ crystal for the ⁴F_3/2→⁴I_9/2 and ⁴F_3/2→⁴I_13/2 transitions at 928 nm and 1328 nm, respectively. A 5-mm-thick, 1.4 at.% Nd:GdTaO₄ crystal was used in the experiments, under a pump at 879 nm, directly into the ⁴F_3/2 emitting level. At a 10 Hz pump repetition rate, the maximum pulse energy at 928 nm reached 35.7 mJ, with an optical-to-optical efficiency of ~19.3%. When the pump repetition rate increased to 100 Hz, the laser pulse energy decreased to 13.5 mJ; the laser beam was characterised by M² factors of M_x² = 1.4 and M_y² = 1.8 for the O_x and O_y axis, respectively. The Nd:GdTaO₄ crystal yielded laser pulses at 1328 nm with a maximum energy of 9.7 mJ for operation at 10 Hz repetition rate; the overall optical-to-optical efficiency amounted to ~5.2%. Increasing the pump repetition rate to 100 Hz reduced the laser pulse energy to 5.8 mJ; the laser beam M² factors were M_x² = 1.2 and M_y² = 1.4.

这项研究研究了Nd：GdTaO ₄晶体分别在928 nm和1328 nm处的⁴ F _3/2 → ⁴ I _9/2和⁴ F _3/2 → ⁴ I _13/2跃迁的激光性能。在实验中，在879 nm的泵浦下，将厚度为5 mm，1.4 at。％的Nd：GdTaO ₄晶体直接注入⁴ F _3/2中。发射水平。以10 Hz的泵浦重复频率，在928 nm处的最大脉冲能量达到35.7 mJ，光-光效率为〜19.3％。当泵浦重复频率增加到100 Hz时，激光脉冲能量降低到13.5 mJ；激光束的特征在于， O _x和O _y轴的M ²因子分别为M _x ²  = 1.4和M _y ² = 1.8 。Nd：GdTaO ₄晶体产生1328 nm的激光脉冲，最大能量为9.7 mJ，以10 Hz的重复频率工作。总体光学对光学效率约为5.2％。将泵的重复频率提高到100 Hz，可将激光脉冲能量降低到5.8 mJ；激光束M ²因子为M _x ²  = 1.2和M _y ²  = 1.4。
