This article presents the results of theoretical analysis and experimental studies on passively Q-switched flash-lamp pumped Er: Glass laser employing Co2+:MgAl2O4 saturable absorber. Using two methodologies derived from basic rate equations, laser performance was optimized in terms of the output energy, pulse width and efficiency. The efficacy of these approaches is compared with each other and these...
This article presents the results of a detailed theoretical and experimental analysis carried out on a folded Z-shaped polarization coupled, electro–optically Q-switched laser resonator with Porro prisms and waveplates. The advantages of adding waveplates in a Porro prism resonator have been explored for creating high loss condition prior to Q-switching and obtaining variable reflectivity with fixed...
