Abstract
A laser apparatus for inverting a population in an atomic or molecular species is provided. Energy is stored in a first species and a laser induced collisional energy transfer from that first species to a selected dissociative molecular state of a second species causes an inversion of one of the constituents of the second species. This is represented, in one embodiment of the present invention which utilizes a second species comprising a diatomic molecule, by the reaction EQU A*+BC+h.nu..fwdarw.A+(BC)*.fwdarw.A+B*+C, where A and A* are the ground and excited states of the first species respectively, denoted as the storage species, BC and (BC)* are the ground and excited states of the second species respectively, which comprises atoms B and C, and B* is the excited state of atom B, which excited state is inverted.
