We present a compact passively Q-switched mode-locked Nd:LuVO4 laser run in Z-type folded cavity with semiconductor saturable absorber mirror (SESAM). The repetition rates of the pulse envelope ranges from 22.99 to 141.18 kHz as pump power increased 2.372 8.960 W. pulses has 111 MHz determined by length and duration is evaluated be 257 ps. An average output 823.5 mW achieved at 8.96 W, corresponding an optical conversion efficiency 9.2%.
By considering the Gaussian spatial distributions of intracavity photon density and initial population-inversion as well influence acoustic-optic (AO) Q-switch, we provide coupled rate equations for a doubly Q-switched laser with both an AO modulator Cr /sup 4+/ -doped saturable absorber (SA). These are solved numerically. The key parameters optimally determined,and group general curves generated first time. include optimal normalized coupling parameter, SA which can maximize output energy....
The analysis of oscillatory properties fractional circuits is still an open problem due to the multi-valuedness and non-locality operators. In this paper, complex path integral approach applied achieve impulsive response order RLCα circuit, which possesses advantages high precision fast convergence as well providing a novel way theoretical circuit. On basis, dependent oscillation criterion (critical damping criterion) for circuit successfully solved by adopting dimensionless analysis,...
