Spectral and temporal characteristics of hydrogen emission during femtosecond optical breakdown on a water surface

Abstract

Spectral and time characteristics of a hydrogen HI 656 nm emission line are experimentally investigated during optical breakdown generated by pulses of the first harmonics of a femtosecond Ti:Sapphire laser on the water surface. The electron density of the generated plasma is estimated.
