Nanosecond Self-Q-Switching Nd:Luag Laser With High Repetition Rate

IEEE Photonics Journal, 2021
Numerical and experimental studies were investigated for the self-Q-switching Nd:LuAG laser which was achieved by the Kerr lens effect. By applying two output couplers of 6% and 1.4%, the shortest pulses of 193.4 ns and 5.1 ns were ...

Heavy-duty high-repetition-rate generators [PDF]

IEEE Transactions on Plasma Science, 2002
The authors present their recent results on high power repetitive pulse sources for continuous operation. Two 1-10 kW systems using spark gap technology have been tested for several hundred hours at a 60 MW pulse level. High reliability and above 90% overall efficiency are realized.

Design of a Hybrid Split-Delay Line for Hard X-ray Free-Electron Lasers

Photonics, 2022
High repetition-rate X-ray free-electron lasers (XFELs) enable the study of fast dynamics on microsecond time scales. Split-delay lines (SDLs) further bring the time scale down to femtoseconds by splitting and delaying the XFEL pulses.

Multiwavelength high-repetition rate source [PDF]

Laser Physics, 2019
Abstract We propose and experimentally validate an all-optical approach to generate simultaneously several pulse trains with identical temporal and spectral properties. Applying a temporal sinusoidal phase modulation followed by a shaping of the spectral phase enables us to handle several channels.
