Abstract

An all-fiber high-power Mamyshev oscillator (MO) with only one amplification stage was experimentally demonstrated. The achieved maximum output power was 3.4 W with 77 nJ pulse energy and could be compressed to ~100 fs. By adjusting the pump power, the phenomenon of harmonic mode locking is observed in the experiment, and the highest 5th order harmonic can be achieved, which corresponds to the repetition rate of 44.1 MHz. This compact MO ultrafast laser could operate stably several hours and the power fluctuation within 5 h was less than 0.12%. Such a high power ultrafast laser oscillator could apply a promising source for advanced fabrication, biomedical imaging, micromachining and other practical applications.
