Abstract
Frequency characteristics and the stability oflasing regimes are considered for a solid-state laser withintracavity second-harmonic generation and feedback at thefrequency of the second harmonic. Three stationary statesdiffering from each other by a nonlinear phase shift related tosecond-harmonic generation are investigated. It is shown thatjumps in the frequency of laser radiation may be induced bytransitions between the considered stationary states as parameters of a dual-cavity laser are smoothly tuned.
