摘要

Collinear phase-matching of sum-frequency generation (SFG) has been studied thoroughly previously, while non-collinear schemes are sometimes more flexible in application. However, this phase-matching type is more difficult to meet and control. We employ a convenient method to obtain harmonic generation in bulk KDP: using an incident wave vector and a reflected wave vector to consist triangle phase-matching relationship. With a simple, flexible set-up, we can observe 351nm SFG and the conversion efficiency is up to ~3.6% per reflection. Furthermore, we believe this approach has potential application value and improvement space.
