In this paper, we report on the intracavity frequency doubling of the Pr:YLF laser with a LiB3O5 (LBO) crystal, which was pumped by a combined 1.4 W blue laser diode at 444 nm and 1.5 W blue laser diode at 469 nm. By optimizing the design of the resonator, using a 5-mm-long LBO crystal, the maximum output power of 5 mW at 302 nm was achieved with respect to the total pump power.
