Adiabatic transition of the pump into second optical harmonic
Baranova N. B.
Mode-type solutions with a z-independent ratio E2w/Ew are found for a medium which supports Hw^lHw interaction for arbitrary wave vector mismatch Ak=k2 — 2kl. Complete adiabatic energy transition from Ew to E2w is proposed for a medium with gradually z-dependent mismatch Ak(z).
