Abstract
This paper presents the newest development of high energy, high power ultrafast fiber lasers in 1 μm, 2 μm and 3 μm regimes at PolarOnyx Inc. For the 1 μm mJ fiber laser, a Yb-doped PCF optical amplifier was built to boost pulse energy to 1.1 mJ at 100 kHz, with pulse duration of 710 fs. In the kW experiment, up to 1050 W average power was obtained with a repetition rate of 80 MHz and pulse duration of 850 fs. In the Tm-doped fiber laser experiment, an average power of up to 76 W was achieved at wavelength of 2012 nm with a repetition rate of 31 MHz and pulse duration of 870 fs. In the Er:ZBLAN fiber laser experiment, an average power of up to 142 mW was achieved at wavelength of 2784 nm with a repetition rate of 16.4 MHz and pulse duration of 5 ps. This work lays out a foundation for further energy and power scaling of ultrafast fiber lasers.
