"Second harmonic generation in periodically poled crystals for two types of interaction"
Quantum Electronics (Rus.), 2001, v.31, N10, p.929-932

      Second harmonic generation of laser radiation in periodically poled crystals is considered for two types of interaction simultaneously. The possibility of highly efficient frequensy conversion of depolarised laser radiation is demonstrated.
