摘要：

A Cerenkov-type second harmonic generation from a LiNbO3 waveguide with a periodic domain grating has been studied both theoretically and experimentally. By the quasi phase-matching due to the domain grating, the output Cerenkov angle is arbitrary controlled to obtain the shallow radiated angle with good radiation profile. At the same time, the conversion efficiency increases several ten times due to the large overlapping of the fields.
