Abstract :
An Nd:YVO4 laser with intracavity frequency doubling exhibits two mode-locked states with different repetition rates. The two states may coexist, interact and transform from one to the other as the cavity length is varied. The transition from one dominant state to the other takes place continuously. The proposed effect is evidence of a bifurcation phenomenon.
