Abstract

Highlights: Blue LD-pumped EO Q-switched Pr:YLF visible laser at 639 nm was demonstrated. Maximum pulse energy of 260 μJ and highest peak power of 1.90 kW were realized. Excellent beam quality visible pulsed laser was achieved. Abstract: We report the generation of high energy visible pulsed beam from a blue LD-pumped electro-optically (EO) Q-switched Pr 3+ :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.
