The Soliton Laser: A Simplified Model

The soliton laser oscillation, as described by Mollenauer and Stolenl, is achieved by reinjecting into the main cavity a pulse that has been compressed after its passage through an optical fiber. This pulse, being extracted from the preceding mode locked pulse, is thus coherent with the existing pulse in the laser cavity. Moreover, the parameters are adjusted in order that the reinjected pulse coincides precisely with the laser pulse.
