Comparison of passive Q-switching and Q-switched mode-locking transition in Nd:MgO:LiNbO3 laser based on cavity length modulation

The transition from passive Q-switching (PQS) to Q-switched mode-locking (QML) in the Nd:MgO:LiNbO 3 laser is systematically investigated. A coupled rate equation model is established by introducing a hyperbolic secant function into the PQS photon density equations. The cavity le...
