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.
已报道了对具有Cr4+:YAG饱和吸收体的被动调Q Nd:YAG微芯片激光器中单个脉冲和双脉冲的实验研究。双脉冲由一个主脉冲和一个卫星脉冲组成，它们具有各自的光谱、强度和持续时间。发现优势振荡模式产生主脉冲，而另一个振荡模式对应于卫星脉冲。我们的结果表明，双脉冲发射是由高泵浦状态下的双纵模振荡引起的。
