Abstract

Continuous-wave 457 blue laser emission at powers as high as 4.6W is achieved by using a fiber-coupled laser diode array with a power of 30W to pump 0.1at.% low-doped bulk Nd:YVO4 crystal, with intracavity frequency doubling in a 15mm long type I critical phase-matched LiB3O5 (LBO) crystal in a compact threefold cavity with a length of less than 100mm. The optical–optical conversion efficiency is greater than 15.3%, and the stability of the output power is better than 3% for an hour.
