Wavefront Sensor for Laser Beams Based on Reweighted Amplitude Flow Algorithm
Ondrej Denk, Jan Pilar, Martin Divoky +2
We present a reference-free computational wavefront sensor based on binary amplitude modulation and phase retrieval. The method employs Digital Micro-mirror Device as a programmabl…
A comprehensive study of second and third harmonic conversion efficiency, angular and temperature tolerance, and long-term stability in LBO crystals using a 10-J-class laser
Huzefa Aliasger, Ondřej Novák, Zbyněk Hubka +11
We present a study of second harmonic generation (SHG) and third harmonic generation (THG) in lithium triborate (LBO) crystals using a high-energy, 10-J-class, 10 Hz Yb:YAG laser s…
Adaptive optics design for high-energy kW-class multi-slab laser amplifier
Tomáš Paliesek, Martin Divoký, Jan Pilař +2
We demonstrate real-time wavefront correction in a high-energy high-average-power DiPOLE100/Bivoj laser using adaptive optics. A bimorph deformable mirror and Shack-Hartmann wavefr…
70 MW-level picosecond mid-infrared radiation generation by difference frequency generation in AgGaS2, BaGa4Se7, LiGaSe2, and LiGaS2
Michal Jelínek, Milan Frank, Václav Kubeček +6
Comparative study of nonlinear crystals for picosecond difference frequency generation in mid-IR is presented. Nonlinear crystals of AgGaS, BaGaSe, LiGaSe, and LiGa…
