Abstract

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.
