Abstract: Frequency characteristics and the stability of lasing regimes are considered for a solid-state laser with intracavity second-harmonic generation and feedback at the frequency of the second harmonic. Three stationary states differing from each other by a nonlinear phase shift related to second-harmonic generation are investigated. It is shown that jumps in the frequency of laser radiation may be induced by transitions between the considered stationary states as parameters of a dual-cavity laser are smoothly tuned.
