Abstract

The spectral lines broadening in femtosecond laser plasma generated by the 45 fs Ti:Sa laser pulses on the surface of the water solutions of Ba is investigated. The contribution of the Doppler broadening for spectral lines width is minimal and amounts 0.0022 nm for Ba. The main mechanism of Ba spectral line broadening in experimental conditions is resonance. The resulting values of resonance broadening constitute a 0.0349 nm for Ba I (413.24 nm), 0.0563 nm for Ba I (553.54 nm), 0.0241 nm for Ba II (455.41 nm), 0.0437 nm for Ba II (614.17 nm).
