摘要：
By employing the mixed crystal Nd:Lu0.5Y0.5VO4 and the single crystal Nd:YVO4 as the laser media, the characteristics of the QML laser doubly modulated by electro-optic (BO) modulator and transmission semiconductor saturable absorber (T-SSA) are studied. Under the Same cavity parameters, the properties of the low repetition rate sub-nanosecond pulses generated from Nd:Lu0.5Y0.5VO4 and Nd:YVO4 laser are compared. The experimental results show that Nd:Lu0.5Y0.5VO4 laser can generate shorter pulse width than Nd:YVO4 laser, and meanwhile, needs lower pump power to generate low repetition rate sub-nanosecond pulses. The shortest pulse durations obtained from the doubly QML Nd:Lu0.5Y0.5VO4 and Nd:YVO4 lasers are estimated to be 204 and 294 ps, with the corresponding peak power of 3.4 and 3.04 MW, respectively.
