Abstract
A diode-pumped doubly Q-switched Nd:YVO4 laser operating at 532 nm with an electro-optic (EO) modulator and a GaAs saturable absorber is presented. This laser can generate more symmetric and shorter pulses compared with those modulated by a single EO Q-switcher. A symmetry factor is defined to describe the temporal symmetry of the pulse profile. At the pump power of 10 W, a 4.2-ns pulse with a symmetry factor of 1.053 and a peak power of 33.7 kW is obtained. A rate equation model has been developed in order to explain the experimental results, in which the influences of population-inversion density on laser character are taken into account, and it leads to a good agreement with the experimental data.
