LASER CONTROL OF PHOTOPREDISSOCIATION ANGULAR-DISTRIBUTIONS AND PHOTOIONIZATION IN CL2 BY 2 COLOR INTERFERENCE

A coupled equations approach based on a general artificial channel method is used to demonstrate two color laser coherent control of photopredissociation and photoionization in Cl2. Photopredissociation of the 1PI(g) States Of Cl2 is suppressed by a two plus four photon interference process 2omega2 = 4omega4, whereas the photoionization is controlled by interference between a six photon transition and a four photon transition 6omega4 = 2omega2 + 2omega4 using the same 1PI(g) photopredissociation resonances as intermediates. Photopredissociation angular distributions illustrate the suppression of the corresponding transition in selective rotational states.
