# Theory of Sub-Cooperation-Limit Optical Pulses in Resonant Absorbers

Conference paper

## Abstract

It has been known for some time that the interaction of spins or two-level atoms with a classical radiation field can depend in an interesting way on the existence of a certain coherence time τ

_{a}, defined by [1,2]$$\frac{1}{{\tau _a^2}} = \frac{\pi }{2}N\omega {\kappa ^2}.$$
