The colliding pulse mode-locking (CPM) technique has been applied to a flashlamp-pumped rhodamine 6G dye laser to reliably generate pulses of <1.5 ps. Pulse evolution in the ring cavity has been studied by examining the pulse characteristics at various parts of the pulse train using a Photochron II streak camera. The measured pulse durations in the ring cavity were found to be detector-limited and were shorter than those generated in a linear cavity. The shortest pulses were observed to evolve toward the end of the ~600-ns long mode-locked train.
碰撞脉冲锁模（CPM）技术已应用于闪光灯泵浦的罗丹明6G染料激光器，以可靠地产生小于1.5皮秒的脉冲。通过使用Photochron II条纹相机检查脉冲序列各部分的脉冲特性，研究了环形腔中的脉冲演化。发现环形腔中测量的脉冲持续时间受探测器限制，并且比线性腔中产生的脉冲持续时间短。观察到最短的脉冲在约600纳秒长的锁模序列接近尾声时演化形成。
