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…

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…

Multipass Faraday rotators and isolators

Johann Gabriel Meyer, Andrea Zablah, Kristaps Kapzems +2

Faraday isolators are usually limited to Faraday materials with strong Verdet constants. We present a method to reach the 45° polarization rotation angle needed for optical isolato…

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…
