The visl%le luminescence resulting from multiple-photon absorption of CO, laser radzation in 0504 depends upon the laser intensity as well as fluenco. The use of single-mode laser pulses, shaped by electro-optic crystal switching, has enabled this intensity dependence to be determined quantitatively

β¦ Synopsis
The frequency dependence of the dissociation rate of the 0~04 molecule by a strong infrared resonant field is shown to have a rich structure due to multiple photon absorption resonances. This permits laser isotope separation with small isotope shift. No dissociation was observed in the case of excitation of the R branch of the 03 mode in OsO+ Threshold characteristics of the dissociation have been studied as well.

A theory of the dissociation of polyatomic molcculcs by intense infrared kscr radiation is prescntcd. It is suggested that vibrational heating of the whole molecule occurs by intramolecular vIbrationa coupling to a given infrared active mode which is in near-rcsomince with the applied field. A high-
The production of molecular and atomic ions has been measured for CO. N2 and O2 with 1064 and 532 nm 40 ps pulses in the 1012-10\*4 W cm" \_ rntensity range. A simultaneous ionization-dissociation process occurs at lower intensities, while a sequential process appears in oxygen at higher intensities
