Abstract
We report the generation of high energy visible pulsed beam from a blue LD-pumped electro-optically (EO) Q-switched Pr3+:LiYF4 (Pr:YLF) laser for the first time. The maximum pulse energy and highest peak power in our work perform excellent in the blue LD-pumped pulse visible lasers. The shortest pulse duration of 137 ns is obtained at the repetition rate of 100 Hz, corresponding to a single pulse energy of 260 μJ and peak power of 1.90 kW. Our research results indicate that the Pr:YLF crystal could be suitable for the generation of high energy Q-switched visible lasers. Meanwhile, we pave up a new way for the practical implementation of blue LD-pumped directly generate high energy Q-switched visible laser.
