Low peak-power pulse compression in gas-filled Herriott cells in the 2 μm wavelength range
Johann Gabriel Meyer, Felix Ritzkowsky, Fatemehsadat Ghaffari +5
At laser wavelengths longer than the prominent 1 μm range of high-power ytterbium-doped lasers, nonlinear phase shifts produced in nonlinear media for spectral broadening and subs…
Free-space quasi-phase matched second harmonic generation in crystalline quartz
Nazar Kovalenko, Ankit Pai, Oleg Pronin
We report experimental results on second-harmonic generation in a z-cut quartz crystal under conditions of free-space quasi-phase matching in a multi-pass cell. In a 62-pass config…
Carrier-Envelope-Offset Frequency Stabilization of a High Peak and Average Power Thin-Disk Oscillator
Yasmin Kopp, Gregor Hehl, Johann Gabriel Meyer +2
In this work, we demonstrate carrier-envelope-offset (CEO) frequency stabilization of a Kerr-lens mode-locked thin-disk oscillator delivering 180 W average power, 80 MW output peak…
Quasi-waveguide amplifiers based on bulk laser gain media in Herriott-type multipass cells
Johann Gabriel Meyer, Andrea Zablah, Oleg Pronin
We present here a new geometry for laser amplifiers based on bulk gain media. The overlapped seed and pump beams are repetitively refocused into the gain medium with a Herriott-typ…
Amplification-free GW-level, 150 W, 14 MHz, and 8 fs, thin-disk laser oscillator
Semyon Goncharov, Kilian Fritsch, Oleg Pronin
We report an amplification-free thin-disk laser oscillatory system delivering 0.9 GW peak power. The 120 fs pulses at 14 MHz containing 12.8 J delivered by thin-disk oscillator…
