摘要：

We demonstrate ultraviolet generation in lithium tantalate channel waveguides for frequency doubling via quasi-phase-matching. The samples, proton exchanged and nanostructured by electric-field assisted surface periodic poling with domains as deep as 40 mu m, yield continuous wave light at 365.4 nm with conversion efficiencies larger than 7.5% W-1 cm(-2).
