Abstract: | In the experiment, we have demonstrated the performance of a laser-diode, end-pumped, doubly Q-switched YVO4/Nd:YVO4 laser with both a BBO electric-optic (EO) Q-switch and Cr4+:YAG saturable absorber. At a maximum incident pump power of 15 W and an EO Q-switch repetition rate of 8 kHz, the stable laser pulses with the pulse duration 5.28 ns, the single pulse energy 0.14 mJ, and the pulse peak power 26 kW are obtained. The experimental results show that the double Q-switched laser with EO and Cr4+:YAG can generate the shorter pulse and the higher peak power in comparison to singly Q-switched laser with EO. |
