We demonstrate efficient self-mode-locked green and red lasers with repetition rates of tens and hundreds of megahertz in a Pr:YLF crystal. Using double-end blue-diode-pumped geometry, more than 0.68 W average output power at 522 nm and more than 1.44 W at 639 nm are obtained, which are believed to be the highest average output powers for mode-locked praseodymium lasers operating in the visible wavelength region.
我们展示了在Pr:YLF晶体中实现的高效自锁模绿光和红光激光器，其重复频率分别为数十兆赫兹和数百兆赫兹。采用双端蓝光二极管泵浦结构，在522nm处获得了超过0.68W的平均输出功率，在639nm处获得了超过1.44W的平均输出功率，据信这是可见波长区域内锁模镨激光器的最高平均输出功率。
