چکیده
The formation of an electron–hole plasma during the interaction intense femtosecond laser pulses with transparent solids lies at heart processing. Advanced micro- and nanomachining applications require improved control over excitation characteristics. Here, we relate emission low-order harmonics to strong laser-field-induced formation. Together a measurement total density, identify contribution two competing ionization mechanisms?strong-field electron-impact ionization.

Modeling the Early Ionization of Dielectrics by Ultrashort Laser Pulses
In this paper, we present a model for propagation of intense and ultrashort laser pulses ionizing dielectrics. We consider early ionization so that this process is sufficiently weak to avoid requiring a complete description of the ionization process (e.g. the use of kinetic equations which are very expensive from a computational point of view). As the intensity of the field is small, one photon...
متن کاملImaging and Controlling Multielectron Dynamics by Laser-induced Tunnel Ionization
Using sequential strong-field double ionization in a pump-probe scheme we show through calculations how electronic dynamics can be prepared and imaged. Electronic dynamics arise whenever multiple states of the ion are accessed in the ionization step. The dynamics in the cation influence the rate of the second ionization step and the momentum distribution of the ejected electron, allowing their ...

متن کاملLaser-induced damage in dielectrics with nanosecond to subpicosecond pulses.
Our extensive measurements of damage thresholds for fused silica and several fluorides (LiF, CaF, MgF and BaF) at 1053 and 526 nm for pulse durations, 2, ranging from 275 fs to 1 ns are reported elsewhere at this meeting. A theoretical model based on electron production via multiphoton ionization, Joule heating, and collisional (avalanche) ionization is in good agreement with experimental results.
متن کاملField dependent avalanche ionization rates in dielectrics.
From the pulse length dependence of the absorption of intense ultrashort laser pulses focused inside fused silica, we reveal the role field-assisted collisional ionization plays in the multiphoton ionization process. This constitutes a cold avalanche ionization mechanism that persists at pulse lengths considered too short for a traditional avalanche.
