摘要
In this work,we confirm a Pr^(3+):LiYF_(4)pulsed laser with high power and high energy at 639 nm based on the acoustooptic 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.A 639 nm pulsed laser with such high pulse energy and peak power has not been reported previously.Furthermore,we obtain a widely tunable range of repetition rates from 0.1 to 5000 kHz.The diffracted beam quality factors M^(2) are 2.18(in the x direction)and 2.04(in the y direction).To the best of our knowledge,this is the first time that a cavity-dumped all-solid-state pulsed laser in the visible band has been reported.This work provides a promising method for obtaining high-performance pulsed lasers.
