We report on a novel laser source, emitting high energy (20 nanoJoule) femtosecond pulses, in a broad spectrum (250 nanometers). This source is easily tuned from 950 to 1200 nanometers, without any laser adjustment, and delivers sub- 300 femtosecond pulses with a 10 nanometers spectral width. 飛秒激光器（飛秒光纖激光器）
