All-optical multiple resonance spectroscopy and state-selected photodissociation dynamics

Using the continuous wave, high resolution, all-optical triple resonance technique, one can overcome the spin forbidden nature of singlet triplet transitions. Consequently, unperturbed and perturbed triplet rovibronic levels can be reached from a singlet ground state. The all-optical triple resonance technique also facilitates state-selective population transfer to highly excited vibrational levels both in the ground state as well as in excited states, thereby making state-selective photodissociation experiments possible. In these experiments we use the polarization of the atomic fluorescence following photodissociation as the probe to photodissociation dynamics. Results from recent spectroscopy as well as photodissociation dynamics experiments for Na2 and K2 will be discussed
