Room-temperature cw second-harmonic generation from telecom wavelengths, with 30% W−1 cm−2 efficiency and second-harmonic power levels up to 41 mW, was achieved in buried waveguides fabricated by reverse-proton exchange in 1% MgO-doped stoichiometric lithium tantalate without any evidence of optical damage. The technology proves suitable for the realization of efficient nonlinear frequency converters and all-optical devices. © 2006 Optical Society of America.
