Which outcome occurs when phase matching is imperfect in second harmonic generation (SHG)?

💡 Explanation

Imperfect phase matching causes reduced efficiency via destructive interference because only waves generated in phase will constructively interfere; therefore, less second harmonic light results, rather than other scattering phenomena that require different mechanisms.
