Femtosecond amplifier similariton Yb:fiber laser at a 616 MHz repetition rate Chen Li, Guizhong Wang, Tongxiao Jiang, Peng Li, Aimin Wang,* and Zhigang Zhang State Key Laboratory of Advanced Optical Communication Systems and Networks, School of Electronics Engineering and Computer Science, Peking University, Beijing 100871, China *Corresponding author: [email protected] Received December 23, 2013; revised February 20, 2014; accepted February 20, 2014; posted February 24, 2014 (Doc. ID 203609); published March 21, 2014 We report a compact Yb:fiber ring laser operated at 616 MHz. The average output power is 450 mW at a pump power of 900 mW. The dechirped pulse width is 98 fs. © 2014 Optical Society of America OCIS codes: (320.7090) Ultrafast lasers; (140.3510) Lasers, fiber. http://dx.doi.org/10.1364/OL.39.001831
Ytterbium-fiber-based mode-locked lasers are ideal sources for optical metrology, due to their compactness, high-power, and high-repetition-rate capability [1–3]. Among them, high-repetition-rate laser oscillators are preferred for high-precision optical calibration, high-speed bioimaging, and high-precision calibration of astronomical spectrographs [4–6]. High-repetition-rate (up to gigahertz) linear cavity mode-locked Yb:fiber lasers working with a semiconductor or carbon nanotube saturable absorber deliver pulses with a relatively large pulse width (usually >200 fs) and low output power (
