Optics wave equation
WebIn this case, the crystal itself provides the additional wavevector k = 2π/Λ (and hence momentum) to satisfy the phase-matching condition. Quasi-phase-matching can be expanded to chirped gratings to get more bandwidth and to shape an SHG pulse like it is done in a dazzler. WebSo, an electric field of the form E ( z, t) = E 0 e i ( k z − ω t + ϕ 0) + c. c. = 2 ⋅ E 0 cos ( k z − ω t + ϕ 0) indeed describes a real/physical wave. Of course, while doing the maths it may become cumbersome to carry around the c.c. term through a series of equations, and so it is dropped (but implicitly, it is still there).
