Abstract
Periodically-poled, planar waveguides in lithium niobate were used to generate 532 nm and 424 nm radiation at room temperature by continuous-wave frequency-doubling with conversion efficiencies of 2.4 − 5% per W-cm2. Quasiphasematching allowed generation of the second harmonic using the d33 nonlinear coefficient.Keywords
