我们演示了一种简单可靠的水冷飞秒激光器,运行频率为10 kHz,适用于工业微加工应用。与使用额外多通放大器的传统结构相比,仅使用再生放大器的激光几何结构可提供平均功率为3.5 W的60秒脉冲。这两种激光系统都需要一个中等泵浦激光器,平均功率约为30w,并提供高质量的光束(M-2)
We demonstrate operation of a simple and reliable water-cooled femtosecond laser running at 10 kHz suitable for industrial micromachining applications. A laser geometry involving only a regenerative amplifier and delivering 3.5 W average power 60-fs pulses is compared to a more conventional architecture using an additional multi-pass amplifier. Both laser systems require a moderate pumping laser of similar to 30 W average power and deliver high-quality beams (M-2
