  We present a metallic zinc indiffused diced ridge waveguide in magnesium
doped periodically poled lithium niobate (MgO:PPLN) capable of generating over
1 W of 780 nm with 70% efficiency. Our 40 mm long waveguide has near circular
fundamental mode output with diameter 10.4 um and insertion loss of -1.17 dB.
Using a commercial 2 W EDFA-based system, the SHG output power did not exhibit
roll-off at maximum available pump power.
