摘要

By using the mixed crystals Nd:Lu_(0.15) Y_(0.85) VO_4, Nd:Lu_(0.5)Y_(0.5)VO_4 and Nd:Lu_(0.33) Y_(0.37)Gd_(0.3)VO_4 as laser media, the LD pumped passively Q-switched mixed lasers with GaAs saturable absorber are realized. The average output power, the pulse width etc. have been measured and compared. The experimental results show that the passively Q-switched Nd:Lu_(0.33)Y_(0.37)Gd_(0.3) VO_4 laser can generate shorter pulse width with higher peak power due to broader fluorescence line-width. Under Gaussian spatial distribution approximation, the rate equations for LD pumped passively Q-switched lasers of the mixed crystals with GaAs saturable absorber are given. The numerical solutions of the equations are in agreement with the experimental results.
