Diode-pumped actively Nd:Lu0.33Y0.37Gd0.3VO4 Q-switched laser with electro-optic (EO) modulator

Nd:Lu0.33Y0.37Gd0.3VO4 crystal is a new triple-mixed vanadate crystal and has broader fluorescence line-width. By using electro-optic (EO) modulator as active Q-switch, a diode-pumped actively Q-switched Nd:Lu0.33Y0.37Gd0.3VO4 laser is realized for the first time. The average output power and the pulse width under different EO repetition rates are measured. The experimental results show that the actively Q-switched Nd:Lu0.33Y0.37Gd0.3VO4 laser can generate shorter pulse width with higher peak power. Due to broader fluorescence line-width, the triple-mixed crystal Nd:Lu0.33Y0.37Gd0.3VO4 is a promising laser medium for the Q-switched laser.
