Abstract
Spectral and time characteristics of the hydrogen HI 656 nm emission line radiation are experimentally investigated at the optical breakdown generated by pulses of the main harmonic of a femtosecond Ti:Sa laser on the water surface. The electronic density of the generated plasma is estimated.
