Recording and Reading of Three-dimensional Optical Memory in Glasses
TL;DR: In this article, a three-dimensional (3D) optical memory recording and reading in glass by femtosecond pulses was described, and the readout was carried out by the white-light continuum generated from the previously damaged sites (recorded memory bits).

Laser frequency upshift, self-defocusing, and ring formation in tunnel ionizing gases and plasmas
C. S. Liu,V. K. Tripathi +1 more
TL;DR: In this article, the combined effects of tunnel ionization of gases on laser frequency upshift, defocusing, and ring formation are considered self-consistently, and the authors show that the defocusing reduces the ionization rate and frequency upsh.

Femtosecond laser-induced nonlinear spectroscopy for remote sensing of methane
TL;DR: In this paper, femtosecond laser-induced nonlinear molecular spectroscopy is applied for sensing atmospheric greenhouse gas methane (CH4), which can dissociate the CH4 molecules into small fragments which emit characteristic fluorescence.
Journal ArticleDOI
Remote time-resolved filament-induced breakdown spectroscopy of biological materials
TL;DR: The remarkably distinct spectra of egg white and yeast allow us to propose that this technique, time-resolved FIBS, could be potentially useful for remote detection and identification of harmful biological agents.
