We present the continuous-wave (CW) and passively Q-switched laser operation of disordered Nd:ABC₃O₇ crystals including Nd:SrLaGa₃O₇, Nd:SrGdGa₃O₇, and Nd:BaLaGa₃O₇. Among the Nd:ABC₃O₇ group members, Nd:SrLaGa₃O₇ exhibits superior laser properties. A maximum output power reaches 3.88 W under an absorbed pump power of 29.01 W, which is the highest CW output power using LD as the pump source for Nd:SrLaGa₃O₇ gain medium. Using a Cr⁴⁺:YAG crystal as a saturable absorber, the LD pumped passively Q-switched laser is also realized. With Nd:SrLaGa₃O₇, the shortest pulse width, the largest pulse energy, and the highest peak power are observed to be 10.6 ns, 60.3 μJ, and 5.3 kW, respectively. In the CW laser operation, wavelength tunings are also reported. The center wavelength of this Nd: SrGdGa₃O₇ laser shifts from 1062.48 to 1063.91 nm by changing the temperature from 60 °C to 135 °C.

我们介绍无序Nd：ABC ₃ O ₇晶体，包括Nd：SrLaGa ₃ O ₇，Nd：SrGdGa ₃ O ₇和Nd：BaLaGa ₃ O ₇的连续波（CW）和被动调Q激光操作。在Nd：ABC ₃ O ₇组成员中，Nd：SrLaGa ₃ O ₇表现出优异的激光性能。在29.01 W的吸收泵浦功率下，最大输出功率达到3.88 W，这是使用LD作为Nd：SrLaGa ₃ O ₇增益介质的泵浦源的最高CW输出功率。使用Cr ⁴⁺：YAG晶体作为可饱和吸收体，还实现了LD泵浦的被动调Q激光器。使用Nd：SrLaGa ₃ O _7时，观察到的最短脉冲宽度，最大脉冲能量和最高峰值功率分别为10.6 ns，60.3μJ和5.3 kW。在连续波激光操作中，还报告了波长调谐。通过将温度从60°C更改为135°C ，此Nd：SrGdGa ₃ O ₇激光器的中心波长从1062.48变为1063.91 nm。
