Supercontinuum Generation in the Low-Peak-Power Regime Using a Single-Stage Multipass Cell

Zeyang Hu, Kilian Fritsch, Oleg Pronin

We demonstrate a single-stage multipass cell (MPC) compressor driven directly by a 500 nJ, 5 W, 120 fs, 10 MHz oscillator that delivers efficient spectral broadening from 800 to 12…

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…

Spectral broadening in convex-concave multipass cells

Kilian Fritsch, Victor Hariton, Kevin Schwarz +3

Since its first demonstration in 2016, the multi-pass spectral broadening technique has covered impressive ranges of pulse energy (3 J - 100 mJ) and peak power (4 MW - 100 GW).…

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…

Free-space quasi-phase matching

Nazar Kovalenko, Victor Hariton, Kilian Fritsch +1

We report a new approach to phase matching of nonlinear materials based on the free space multipass cells. This concept quasi-phase matches crystalline quartz and increases the sec…

110 MW Thin-Disk Oscillator

Semyon Goncharov, Kilian Fritsch, Oleg Pronin

A compact Kerr-lens mode-locked thin-disk oscillator delivering 110 MW output peak power, the highest among all oscillators, is reported. A pulse train with a repetition rate of 14…

Dual-comb thin-disk oscillator

Kilian Fritsch, Jonathan Brons, Maksim Iandulskii +4

For the first time to our knowledge, a dual-comb laser based on thin-disk technology and its application to direct frequency comb spectroscopy are presented. The peak power (0.6 MW…

Characterization of nonlinear effects in edge filters

T. Amotchkina, M. Trubetskov, E. Fedulova +4

A specially designed and produced edge filter with pronounced nonlinear effects is carefully characterized. The nonlinear effects are estimated at the intensities close to the lase…
