Excited‐State Dynamics and Optical Properties of Silica Under Ultrafast Laser Irradiation

Excited‐State Dynamics and Optical Properties of Silica Under Ultrafast Laser Irradiation

Abstract Excited by intense infrared ultrafast light pulses, a wide bandgap material undergoes nonlinear ionization, generating a high density of free electrons in conduction states. As a result, the electronic band structure is critically modified and the bandgap shrinks. This induces rapid changes...
