abstract
It is shown that a pulsed laser can efficiently extract energy from an inverted molecular medium even when the transitions involved are highly forbidden. This is accomplished by injecting pulses that are strong enough to drive the molecules from the excited to the weakly coupled ground state. It is well known that this Rabi flopping can be accomplished with a x pulse. We show that essentially the same energy requirements are associated with optically bleaching the inverted medium in the rate-equation limit. 1986 Optical Society of America.
