我们展示了一种新的技术，用于克尔透镜锁模（KLM）激光器中的色散补偿，使用一种新的谐振腔设计与棱镜端镜。这种方法实现了腔内色散补偿，而不需要棱镜对或色散补偿镜。1 GHz的脉冲重复率，据我们所知，在KLM激光器中达到的最高重复率数据，产生的脉冲持续时间为111 fs。在385 MHz的重复频率下实现了54 fs的脉冲持续时间。我们相信，这种新的色散补偿技术将有助于紧凑型飞秒光源的发展。
We demonstrate a new technique for dispersion compensation in Kerr-lens mode-locked (KLM) lasers that uses a novel resonator design in conjunction with a prismatic end mirror. This approach achieves intracavity dispersion compensation without the need for prism pairs or dispersion-compensating mirrors. A pulse-repetition rate of 1 GHz, to our knowledge the highest repetition rate achieved in a KLM laser to data, is generated with a pulse durations of 111 fs. Pulse durations of 54 fs are achieved at a repetition rate of 385 MHz. We believe that this new dispersion-compensation technique will be useful for the development of compact femtosecond sources.
