    In this work, we confirm a Pr:YLF pulsed laser with high power and high energy at 639 nm based on the acousto-optic cavity dumping technique. The maximum average output power, narrowest pulse width, highest pulse energy, and peak power of the pulsed laser at a repetition rate of 0.1 kHz are 532 mW, 112 ns, 5.32 mJ, and 47.5 kW, respectively, the 639 nm pulsed laser with such high pulse energy and peak power have never been reported so far. Furthermore, we obtain a widely tunable range of repetition rates from 0.1 kHz to 5000 kHz. The diffracted beam quality factors M2 are 2.18 (in x direction), and 2.04 (in y direction), respectively. To the best of our knowledge, it is the first time that a cavity-dumped all-solid-state pulsed laser in visible band is reported so far. This work provides a promising method for obtaining high-performance pulsed lasers.
