We demonstrate, for the first time as far as we know, a passively Q-switched operation of a Nd:YVO(4) laser in which a Cr(4+):YAG crystal and a laser-diode bar are used as the saturable absorber and the pump source, respectively. Stable laser pulses as short as 28 ns with 20-muJ energy can be generated with this laser, which has the advantages of simplicity, high efficiency, and good long-term stability.
据我们所知，我们首次展示了一种掺钕钒酸钇（Nd:YVO₄）激光器的被动调Q运转，其中分别使用铬离子掺杂钇铝石榴石（Cr⁴⁺:YAG）晶体和激光二极管阵列作为可饱和吸收体和泵浦源。用这种激光器可以产生稳定的激光脉冲，脉宽短至28纳秒，能量为20微焦，具有结构简单、效率高和长期稳定性好的优点。
