We systematically study the characteristics of the Cherenkov second-harmonic generation in periodically poled lithium niobate by femtosecond pulses. A relatively high conversion efficiency is obtained and what we believe to be a new different explanation is proposed that nonlinearities in the domain wall region have been enhanced significantly, which is a new feature of the domain wall that has not been studied previously. ©2010 Optical Society of America
