LD-pumped acousto-optic 2-switched Pr:YLF pulsed laser at 604 nm

【摘要】 We demonstrated an actively acousto-optic Q-switched pulsed laser based on Pr:YLF at 604 nm.A 604 nm continuous-wave(CW) laser with a maximum output power of 3.84 W was achieved for the first time,to the best of our knowledge.The Q-switched laser with a maximum average output power of 0.384 W,a narrowest pulse duration of 44.5 ns,a maximum single pulse energy of～64.1μJ,and a maximum peak power of～1.44 kW was obtained at a repetition rate of 6 kHz.As far as we know,this was the first report of such a narrow pulse duration,high-power,and high-energy Q-switched pulsed laser at604 nm. The beam quality factors M_x~2and M_y~2were measured to be 2.87 and 2.40,respectively.The results show that acousto-optic Q-switching is a promising method for obtaining pulsed lasers.更多还原
