Effects of laser radiation on matter

Spectrum of the barium atom in a laser radiation field

I. I. Bondar', V. V. Suran


Abstract: An experimental investigation was made of the influence of a laser radiation field on the spectrum of barium atoms. The investigation was carried out by the method of three-photon ionization spectroscopy using dye laser radiation (ω = 14 800–18 700 cm ^– 1). The electric field intensity of the laser radiation was 10³–10⁶ V/cm. This laser radiation field had a strong influence on a number of bound and autoionizing states. The nature of this influence depended on the ratio of the excitation frequencies of bound and autoionizing states.
