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 subse…
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…
White Light Generation and Few Cycle Pulse Compression in Cascaded Multipass Cells
Semyon Goncharov, Kilian Fritsch, Oleg Pronin
We report supercontinuum generation and pulse compression in two stacked multipass cells based on dielectric mirrors. The 230 fs pulses at 1 MHz containing 12 J were compressed…
