Bright isolated light pulses reaching 18 attoseconds from high-order harmonic generation by post-compressed Yb lasers [PDF]

open access: yesNature Communications
Generating ever-shorter and brighter light pulses is a central goal of ultrafast science, enabling coherent control and observation of electron dynamics on their natural timescale.

Controlling electron recollision with combined linear and circular polarization

open access: yesFrontiers in Physics, 2022
We theoretically investigate the non-sequential double ionization of Ar atoms in the combined fields of linearly polarized laser and circularly polarized laser through 3D semiclassical simulations. By partially overlapping the two time-delayed multicycle

A model for the dissociation pulse, afterglow, and laser pulse in the Cu/CuCl double pulse laser [PDF]

open access: yesJournal of Applied Physics, 1980
A model which completely describes the Cu/CuCl double pulse laser is presented. The dissociation discharge pulse and afterglow are simulated and the results are used as initial conditions for an analysis of the pumping discharge pulse and laser pulse.

Ultrashort pulsed laser induced complex surface structures generated by tailoring the melt hydrodynamics

open access: yesOpto-Electronic Advances, 2022
We present a novel approach for tailoring the laser induced surface topography upon femtosecond (fs) pulsed laser irradiation. The method employs spatially controlled double fs laser pulses to actively regulate the hydrodynamic microfluidic motion of the

Characteristics of the pumping pulse and the output laser pulse for a Cu/CuCl double pulse laser [PDF]

open access: yesIEEE Journal of Quantum Electronics, 1980
Characteristics of the pumping discharge pulse and laser pulse in a Cu/CuCl double pulse laser have been measured as a function of time delay, buffer gas pressure, and tube temperature. We have found that for otherwise fixed discharge conditions, pumping rates decrease as these quantities are increased.

SPECTRAL STUDIES OF THE PROCESSES OF ALUMINUM NANOPOWDER FORMATION EXPOSED BY SHORT SERIES OF TWIN LASER PULSES IN THE AIR ATMOSPHERE

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2020
The processes of formation of oxidized nanopowders depending on the number of pulses were studied when double laser pulses with an energy of 52 mJ and an interpulse interval of 10 microseconds were applied to an aluminum target placed in a closed ...
