โฆ Synopsis
By considering the Gaussian spatial distributions of the intracavity photon density and the initial populationinversion density, the coupled rate equations for a diode-pumped passively Q-switched and mode-locked (QML) laser with Cr 4+ :YAG saturable absorber are given. These coupled rate equations are solved numerically and the key parameters of an optimally coupled passively QML laser are determined for the first time. These key parameters include the parameters of the gain medium, the saturable absorber and the resonator, which can maximize the pulse energy of singly Q-switched envelope. The optimal calculations for a diode-pumped passively QML Nd:GdVO 4 laser with Cr 4+ :YAG saturable absorber are presented to demonstrate the numerical simulation applicable.

We report on the passively Q-switched mode-locking of a quasi-cw (QCW) diode pumped Nd:GdVO 4 laser with Cr 4+ :YAG saturable absorber. We show that by using the QCW pumping high quality Q-switched mode-locking can be easily obtained in the laser even with a simple two-mirror laser cavity configurat
A diode-pumped dual-loss-modulated Q-switched and mode-locked (QML) Nd:GdVO4 laser with acousto-optic (AO) modulator and Cr 4+ :YAG saturable absorber is presented. The experimental results show that the dual-loss-modulated QML laser has the nearly 100% modulation depth and deeper than the modulatio

By using LT-GaAs as saturable absorber, we have demonstrated the stable Q-switched and mode-locked (QML) Nd:LuVO 4 laser run in a Z-type folded cavity. Nearly 100% modulation depth of mode locking can be obtained as long as the pump power reaches the oscillation threshold. The repetition rate of the
