Compared with a single passively Q-switched laser, a double passively Q-switched laser with a GaAs saturable absorber and a Cr 4+ -doped saturable absorber can produce more symmetric and shorter pulses with high pulse peak power. New normalized coupled rate equations for a double passively Q-switche

The key parameters of an optimally coupled doubly Q-switched laser are determined by maximizing the peak power. A group of general curves are generated by considering the single-photon absorption (SPA) and two-photon absorption (TPA) processes in the GaAs, along with the Gaussian spatial distributio
In this paper the results of a theoretical and experimental investigation of synchronized passive Q-switching of two Nd:YVO 4 -based solid-state lasers operating at two different wavelengths, is described. A V:YAG saturable absorbing material was used as a passive Q-switch performing the synchroniza
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 a
