Lisitsa 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. Under the experimental conditions, determined the temperature of femtosecond laser plasma is 3000K.The contribution of the Doppler broadening for spectral lines width is minimal and amounts 0,0022nm for Ba. The main mechanism of Ba spectral line broadening in experimental conditions is resonance. The resulting values of resonance broadening constitute a0,0349nm for Ba I (413,24nm), 0,0563nm for Ba I (553,54nm), 0,0241nm for Ba II(455,41nm), 0,0437nm for Ba II (614,17nm).
