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…
Adaptive optics design for high-energy kW-class multi-slab laser amplifier
Tomáš Paliesek, Martin Divoký, Jan PilaŠ+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…
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, OndÅej Novák, ZbynÄk 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…
Half-kilowatt high energy third harmonic conversion to 50 J @ 10 Hz at 343 nm
Jan Pilar, Martin Divoky, Jonathan Phillips +10
We report on frequency tripling of high energy, high repetition rate ns pulses from a cryogenically gas cooled multi-slab Yb:YAG laser system Bivoj/DiPOLE, using a type-I phase mat…
