All-fiber high-energy yb-doped fiber amplifier
(IEEE, 2009)We report a robust, all-fiber amplifier seeded by a fiber oscillator. Seed pulses at 1 MHz repetition rate are amplified up to 3 μJ, delivering 1 μJ-energy, 170 fs-long pulses. Duration reduces to 120 fs at 1 μJ amplifier ... -
Doping management for high-power fiber lasers: 100 W, few-picosecond pulse generation from an all-fiber-integrated amplifier
(Optical Society of America, 2012-07-16)Thermal effects, which limit the average power, can be minimized by using low-doped, longer gain fibers, whereas the presence of nonlinear effects requires use of high-doped, shorter fibers to maximize the peak power. We ... -
Femtosecond microjoule-Class ytterbium fiber lasers
(Optical Society of America, 2011)We report the generation of 830 nJ energy from a mode-locked all-normal dispersion fiber laser featuring large-mode-area photonic crystal fibers. After external compression, 550 fs pulses with 1.2 MW peak power are ... -
Femtosecond pulse generation from an extended cavity Cr4+: Forsterite laser using graphene on YAG
(Optical Society of America, 2013)A room temperature, multipass-cavity, femtosecond Cr4+:forsterite laser was modelocked with a single-layer graphene saturable absorber on a YAG substrate. The resonator produced nearly transform-limited 92 fs pulses near ... -
High average and peak power femtosecond large-pitch photonic-crystal-fiber laser
(2011)We report on the generation of high-average-power and high-peak-power ultrashort pulses from a mode-locked fiber laser operating in the all-normal-dispersion regime. As gain medium, a large-mode-area ytterbium-doped ... -

Microjoule pulse energies at 1 MHz repetition rate from an all-fiber nonlinear chirped-pulse amplifier
(Optical Society of America, 2010)We report a 1-MHz robust, all-fiber amplifier-oscillator system. Amplified pulses of 3 μJ are externally compressed to 140 fs. The highest peak power from an integrated fiber source, up to 50 kW, is obtained. © 2010 Optical ... -
Microjoule-energy, 1 MHz repetition rate pulses from all-fiber-integrated nonlinear chirped-pulse amplifier
(Optical Society of America, 2010-03-23)We demonstrate generation of pulses with up to 4 μJ energy at 1 MHz repetition rate through nonlinear chirped-pulse amplification in an entirely fiber-integrated amplifier, seeded by a fiber oscillator. The peak power and ... -
Sub-80 fe dissipative soliton large-mode-area fiber laser
(2010)We report on high-energy ultrashort pulse generation from an all-normal-dispersion large-mode-area fiber laser by exploiting an efficient combination of nonlinear polarization evolution (NPE) and a semiconductor-based ... -
Theoretical analysis of doping management
(IEEE, 2013)Two opposing requirements, such as thermal load and nonlinear effects are important limitations in rapid progress of high-power fiber laser technologies. Thermal effects, which limit the average power, can be minimized by ...
