Quasi-Phase Matching
Source: 中国光学期刊网 Understanding Quasi-Phase Matching in Nonlinear Optics Introduction to Quasi-Phase Matching Quasi-phase matching (QPM) is a technique used in nonlinear optics to overcome phase mismatch in nonlinear interactions for processes like frequency conversion. Unlike traditional phase matching where a homogeneous nonlinear crystal is used, QPM involves a material with spatially modulated nonlinear properties. This […]
