Millijoule-level, kilohertz-rate, CPA-free linear amplifier for 2 μm ultrashort laser pulses

Opt. Lett.
Type: Zeitschriftenaufsatz (reviewed)
The generation of millijoule-level ultrashort laser pulses at a wavelength of 2.05~μm in a compact chirped pulse amplification-free linear amplifier based on Holmium-doped YLF gain medium is presented. More than 100~MW of pulse peak power has been achieved. We show the capabilities of this laser amplifier from a 1~kHz to 100~kHz repetition rate. A detailed numerical description supports the experimental work and verifies the achieved results.
