Abstract
The properties of coherent nonlinear gain are utilized for generating stable pulses with durations shorter than the inverse spectral width of the gain profile. A passive cw mode-locking technique making use of the coherent gain and the coherent absorber is proposed as the basis for a self-induced transparency soliton laser. The basic features of pulse evolution including the pulse shortening effect are described.
