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).…
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…
Directly diode-pumped, Kerr-lens mode-locked, few-cycle Cr:ZnSe oscillator
Nathalie Nagl, Sebastian Gröbmeyer, Vladimir Pervak +3
Lasers based on Cr-doped II-VI material, often known as the Ti:Sapphire of the mid-infrared, can directly provide few-cycle pulses with super-octave-spanning spectra, and se…
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…
High photon flux table-top coherent extreme ultraviolet source
Steffen Hädrich, Arno Klenke, Jan Rothhardt +6
High harmonic generation (HHG) enables extreme ultraviolet radiation with table-top setups. Its exceptional properties, such as coherence and (sub)-femtosecond pulse durations, hav…
