一种超短脉冲锁模掺镱光纤激光器已经开发出来。群延迟色散通过腔内的一对光栅进行补偿。无需三阶色散腔内补偿即可获得从 1000 nm 到 1120 nm 的宽光谱。以 80 MHz 的重复频率获得了短至 28.3 fs 的 0.7 nJ 脉冲。据我们所知，这是 Yb 光纤激光振荡器报告的最短脉冲。 (C) 2008 年美国光学学会。
An ultrashort-pulse, mode-locked ytterbium-doped fiber laser has been developed. The group-delay dispersion was compensated with a grating pair inside the cavity. A broad spectrum from 1000-nm to 1120-nm was obtained without intracavity compensation of third-order dispersion. A 0.7-nJ pulse as short as 28.3 fs was obtained with a repetition rate of 80 MHz. To our knowledge, this is the shortest pulse reported from an Yb fiber laser oscillator. (C) 2008 Optical Society of America.
