Abstract

In this paper, actively Q-switched laser operation with an acousto-optic switch has been demonstrated by using Yb:Ca3La2(BO3)4 crystals cut along the a, b, and c crystallographic axes. The most efficient Q-switched laser operation was obtained by using b-cut Yb:Ca3La2(BO3)4 crystal with 1 kHz pulse repetition frequency, generating laser pulses of 0.5 mJ, 42.56 KW peak power and 9 ns pulse width, when the output couplings were 3%, 5%, and 5%, respectively. Pulse performances and output laser spectra of the a-, b-, and c-cut Yb:Ca3La2(BO3)4 crystals were compared under similar experimental conditions.

摘要

在本文中，通过使用沿a、b和c晶轴切割的Yb:Ca3La2(BO3)4晶体，演示了采用声光开关的主动调Q激光运转。当输出耦合分别为3%、5%和5%时，使用b轴切割的Yb:Ca3La2(BO3)4晶体，在1 kHz脉冲重复频率下获得了最有效的调Q激光运转，产生了能量为0.5 mJ、峰值功率为42.56 KW且脉宽为9 ns的激光脉冲。在相似的实验条件下，比较了a轴、b轴和c轴切割的Yb:Ca3La2(BO3)4晶体的脉冲性能和输出激光光谱。
