Abstract:We report on the demonstration of a diode-pumped, Tm:YLF-based, chirped pulse amplification laser system operating at λ ≈ 1.9 µm that produces amplified pulse energies exceeding 1.5 J using a single 8-pass power amplifier. The amplified pulses are subsequently compressed to sub-300 fs durations by a diffraction grating pair, producing record >1 TW peak power pulses. To the best of our knowledge, this is the highest peak power demonstrated for any solid-state, near-2 µm laser architecture and illustrates the… Show more
We report high energy pulses from compact, diode-pumped Tm:YLF amplifiers. We demonstrated pulse energies of 21.7J for 20ns pulses and 108J for long pulses. CPA produced broadband 1.6J pulses that were subsequently compressed to 270fs.
