Compact 50 W All-Solid-State Picosecond Laser System at 1 kHz

Applied Sciences, 2020
Compact, stable, high-power and high repetition rate picosecond laser systems are excellent sources for optical parametric chirped pulse amplification systems and laser satellite ranging systems. Compared with the traditional complex high-power amplifier,

Retrievals of vertically resolved aerosol microphysical particle parameters with regularization from spaceborne Aerosol and Carbon dioxide Detection Lidar (ACDL) [PDF]

Atmospheric Measurement Techniques
Using an improved regularization method, we attempt to derive microphysical parameters (effective radius reff, surface area concentration St, volume concentration Vt) of aerosol particle size distribution directly from the detection results of Aerosol ...

Diode-Pumped Solid-State Q-Switched Laser with Rhenium Diselenide as Saturable Absorber

Applied Sciences, 2018
We report a solid-state passively Q-switched Nd:YVO4 laser adopting rhenium diselenide (ReSe2) as saturable absorber (SA) materials. ReSe2 belongs to a type of transition metal dichalcogenides (TMDs) materials and it has the weak-layered dependent ...

Sub-100 fs watt-level Kerr-lens mode-locked Yb:CaYAlO4 laser with a gigahertz repetition rate

Frontiers in Physics, 2023
We report a 1.04 GHz high-power Kerr-lens mode-locked Yb:CaYAlO4 laser pumped by a single-mode fiber laser at 976 nm. Based on a bow-tie cavity, stable unidirectional mode-locked operation is obtained with an output coupler of 1.6%.

Theoretical investigation of controlled generation of a dense attosecond relativistic electron bunch from the interaction of an ultrashort laser pulse with a nanofilm [PDF]

, 2014
For controllable generation of an isolated attosecond relativistic electron bunch [relativistic electron mirror (REM)] with nearly solid-state density, we propose using a solid nanofilm illuminated normally by an ultraintense femtosecond laser pulse ...

All solid state copper vapor laser.

The Review of Laser Engineering, 1989
A copper vapor laser pumped with an all-solid-state switch modulator has been demonstrated forthe first time. The solid state switch modulator consists of static induction (SI) thyristors and twostage magnetic pulse compression circuits with saturable reactors. The maximum energy transferefficiency of the modulator was 67%.
