Cross-sections of bound-free and bound–bound transitions at a fundamental harmonic of the Nd:YAG laser

Abstract

Bound-free electric dipole allowed and bound–bound electric dipole allowed and electric dipole forbidden transitions at a fundamental harmonic of the Nd:YAG laser, , have been studied. Excitation spectra of the I2 (B, vB, JB → X, vX = 1, JX) luminescence from the B, vB = 18, 20, 21, JB rovibronic states have been measured with switched on and switched off generation. Temporal behaviors of the luminescence intensities from these states with switched on and switched off generation have also been measured. These data allow us to determine or estimate cross-sections of the electric dipole allowed and electric dipole forbidden transitions under study. Dipole moment of the transition has also been determined.
