We demonstrate a compact 290 fs, 0.5 mJ laser source at 2-μm wavelength generated from mJ-level 3.4-ps pulses from a fiber laser seeded Ho:YLF regenerative amplifier system via pulse compression in a gas-filled Kagome type HC-PCF.
We present soliton operation of holmium-doped fiber oscillators with independently tunable central wavelengths from 2040nm to 2070nm and spectral widths from 5nm to 10nm, which can be matched to the requirements of Ho:YLF amplifiers.
We demonstrate on-chip frequency comb generation spanning from 900 to 2300 nm, the widest bandwidth with a laser oscillator (only 50-pJ pulse energy), by controlling dispersion and propagation distance of silicon-wire waveguides.
