TLDR
The self-channeling of ultrashort laser pulses through 20 m of air was demonstrated and a preliminary model is shown to explain these results.Abstract:
The self-channeling of ultrashort laser pulses through 20 m of air was demonstrated. The channeled pulse was measured to have 0.75 mJ of energy, a diameter of 80 microm FWHM, and a modulated spectrum. All these values were measured to be fairly constant during the propagation of the pulse. A preliminary model is shown to explain these results.read more

Mechanisms of pulsed laser ablation of biological tissues.
Alfred Vogel,Vasan Venugopalan +1 more
TL;DR: It was found that the structure and morphology also affect the energy transport among tissue constituents and therefore the ablation efficiency of biological tissues is increased.

Laser Electron Accelerator
Toshiki Tajima,John M. Dawson +1 more
TL;DR: In this paper, an intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force, and electrons trapped in the wake can be accelerated to high energy.

Light pipe for high intensity laser pulses.
TL;DR: Optical guiding of intense laser pulses over a distance of more than 20 Rayleigh lengths in a plasma is demonstrated using a two-pulse technique, and the channel is observed to support mode structure reminiscent of an optical waveguide.

Self-focusing of light pulses in the presence of normal group-velocity dispersion.
P Chernev,Valentin Petrov +1 more
TL;DR: The influence of normal group-velocity dispersion on the self-focusing of light pulses is numerically studied and temporal splitting of the field envelope is observed when the critical power is exceeded along with diffraction of the spatially sharpened central part of the pulse.

6A5 - Possibility of self-focusing due to intensity dependent anomalous dispersion
A. Javan,Paul L. Kelley +1 more
TL;DR: In this paper, the dependence of the real part of the susceptibility on power level (i.e., saturation effects) can be sizeable and therefore lead to self-trapping or self-focusing.
