Abstract
We present an efficient continuous-wave deep-red Pr :YLF laser with a double-pass-pumping architecture. The fiber-coupled blue laser diode is used as the pump source. With an incident pump power of 15.3 W, the deep-red Pr :YLF laser reaches the 5.02 W output power at 720.8 nm, corresponding to a slope efficiency of 40.2%. In addition, we estimate the beam quality factor to be about 2.0.
