Picosecond 554 nm yellow - green fiber laser source with average power over 1

We demonstrate a source of 554 nm pulses with 2.7 ps pulse duration and 1.41 W average power, at a repetition rate of 300 MHz. The yellow-green pulse train is generated from the second harmonic of a 1.11 μm fiber laser source in periodically-poled stoichiometric LiTaO3. A total fundamental power of 2.52 W was used, giving a conversion efficiency of 56%. © 2014 Optical Society of America OCIS codes: (140.3515) Lasers, frequency doubled; (060.2320) Fiber optics amplifiers and oscillators; (190.7110) Ultrafast nonlinear optics.
