报道了采用Cr ~（4+）：YAG可饱和吸收体的被动调Q Nd：YAG微片激光器的单脉冲和双脉冲实验研究。双脉冲由具有各自的光谱、强度和持续时间的主脉冲和卫星脉冲组成。结果表明，主脉冲是由一个优势振荡模式产生的，而另一个振荡模式则对应于卫星脉冲。结果表明，在高抽运状态下，双脉冲辐射是由双纵模振荡引起的。
Experimental investigation of single and dual pulses in a passively Q-switched Nd:YAG microchip laser with a Cr4+:YAG saturable absorber has been reported. The dual pulses consist of a main and a satellite pulse with respective spectra, intensities, and durations. It is found that the preponderant oscillating mode gives birth to the main pulse, and the other oscillating mode corresponds to the satellite pulse. Our results demonstrate that the dual-pulse emission results from double-longitudinal-mode oscillation in high pump regime.
