Abstract

A highly efficient and compact Nd:YVO(4) laser is proposed. In cw operation, a single-longitudinal-mode output of 95 mW and a multilongitudinal-mode output of 435 mW have been observed at 1.06 µm with a 1-W diode laser. Using a KTP crystal in the short laser cavity, a green output of 105 mW was generated. A Q-switched pulse with a peak power of 230 W and a pulse width of 8 ns was obtained with the intracavity KTP crystal, which was used as both an electro-optic Q switch and a frequency doubler.

摘要

提出了一种高效紧凑的掺钕钒酸钇（Nd:YVO₄）激光器。在连续波运行中，使用1瓦的二极管激光器，在1.06微米波长处观测到了95毫瓦的单纵模输出和435毫瓦的多纵模输出。在短激光腔中使用磷酸钛氧钾（KTP）晶体，产生了105毫瓦的绿色输出。腔内KTP晶体既用作电光调Q开关又用作倍频器，获得了峰值功率为230瓦、脉宽为8纳秒的调Q脉冲。
