abstract

Intra-cavity frequency doubling (ICFD) of an extended cavity 49-emitters edge-emitting laser bar has been demonstrated in a quasi-phase matching MgO-doped periodically poled lithium niobate (MgO: PPLN) bulk crystal. A maximum of 1 W of second-harmonic light at 465 nm is generated at an operating injection current of 45 A with the optimal phase-matching MgO:PPLN temperature of 50.4 °C. To increase the efficiency further, careful design of the lens used on the fast and slow axis beam waists and use of lower-temperature MgO:PPLN planar-waveguide array can be considered.
