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