Vg. Dmitriev et Yv. Yur'Ev, Quasi-phase-matching bandwidth for second harmonic generation in crystals with a regular domain structure, QUANTUM EL, 29(9), 1999, pp. 814-816
The question of the quasi-phase-matching bandwidth for second harmonic gene
ration in crystals with a regular domain structure is considered in terms o
f the approximation of a constant field of the fundamental-frequency radiat
ion and in the nonlinear conversion regime.
