EFFICIENT SELF-MODE LOCKING OF CONTINUOUS-WAVE SOLID-STATE LASERS WITH RESONANT NONLINEARITY IN AN ADDITIONAL CAVITY

Parameters of the efficient mode-locking of cw solid-state lasers with saturable absorber in the additional cavity are found on the basis of the laser generation fluctuation model. These parameters form closed ranges. The main features of the efficient mode-locking are associated with the transmission of the additional cavity as a function of the f ield intensity. It is shown that due to the resonant nonlinearity the efficient mode-locking takes place in the absence of the interferometr ical matching of the lengths of the master and additional cavities. It also takes place in the case of the difference of their lengths of up to the value for which the delay of the pulse from the additional cav ity according to generation pulse becomes comparable with generation p ulse duration.
