All fiber-based Yb-doped high energy, high power femtosecond fiber lasers.
Two all fiber-based laser systems are demonstrated to achieve high energy and high average power femtosecond pulsed outputs at wavelength of 1 µm. In the high energy laser system, a pulse energy of 1.05 mJ (0.85 mJ after pulse compressor) at 100 kHz repetition rate has been realized by a Yb-doped ultra large-core single-mode photonic crystal fiber (PCF) rod amplifier, seeded with a 50 µJ fiber ...
متن کاملHigh-power femtosecond Yb-doped single-polarization photonic crystal fiber laser
We report, to the first time to our knowledge, on a passively mode-locked single-polarization single-transverse-mode large-mode-area photonic crystal fiber laser operating in the dispersion compensation free regime. In the single-pulse regime, the laser generates 1.6 W of average power with 3.7 ps pulses at a repetition rate of 63 MHz, corresponding to a pulse energy of 25 nJ. Stable and self-s...
متن کامل1 mJ pulse bursts from a Yb-doped fiber amplifier.
We demonstrate burst-mode operation of a polarization-maintaining Yb-doped fiber amplifier capable of generating 60 μJ pulses within bursts of 11 pulses with extremely uniform energy distribution facilitated by a novel feedback mechanism shaping the seed of the burst-mode amplifier. The burst energy can be scaled up to 1 mJ, comprising 25 pulses with 40 μJ average individual energy. The amplifi...

We report a high-peak-power, single-polarized master oscillator power amplification system employing polarizationmaintaining Yb-doped rod-type photonic crystal fiber. The MOPA system comprises of a Q-switched microchip laser generating ~630ps pulses at 8.6 kHz repetition-rate and two amplification stages employing double cladding fiber and rod-type PCF respectively. The MOPA system obtains narr...
متن کامل3C Yb-doped Fiber Based High Energy and Power Pulsed Fiber Lasers
3C fiber technology advances the performance frontier of practical, high-pulse-energy fiber lasers by providing very large core fibers with the handling and packaging benefits associated with single mode fibers. First-generation fibers demonstrate scaling to > 240 W average power coincident with 100-kW peak power in 1-mJ, 10-ns pulses while maintaining single-mode beam quality, polarized output...
