Laser ablation of CsI: time-resolved Fourier-transform infrared spectra of atomic cesium in the 800-8000 cm-1 range

Fourier-transform time-resolved spectroscopy of laser-induced breakdown of Cs vapor in a vacuum has been used for the measurement of atomic Cs emission spectra in the 800-8000 cm(-1) range with a resolution of 0.02 cm(-1). The 6h and 7h levels of Cs are observed. The dipole transition matrix elements (transition probabilities, oscillator, and line strengths) between the observed levels are calculated using quantum defect theory.
