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

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 amp...

Description
Summary: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.
