In this paper, we demonstrate for the first time a doubly Q-switched pulsed laser, using a novel Nd:Gd_0.69Y_0.3NbO₄ mixed crystal and acousto-optical (AO) Q-switch and Cr⁴⁺:YAG saturable absorber. Compared to purely AO Q-switched lasers, the simultaneous use of AO Q-switches and Cr⁴⁺:YAG saturable absorbers provides the generation of a shorter pulse. We investigated in detail the output characteristics of pulsed Nd:Gd_0.69Y_0.3NbO₄ lasers.

具有声光Q开关和Cr 4+：YAG饱和吸收剂的双Q开关Nd：GdYNbO 4激光器

在本文中，我们首次演示了使用新型Nd：Gd ₀的双Q开关脉冲激光器_。69 Y _{0 。3} NbO ₄混合晶体和声光（AO）Q开关以及Cr ⁴⁺：YAG饱和吸收剂。与纯AO Q开关激光器相比，同时使用AO Q开关和Cr ⁴⁺：YAG饱和吸收剂可产生较短的脉冲。我们详细研究了脉冲Nd：Gd ₀的输出特性_。69 Y _{0 。3}铌₄ 激光。
