摘要：Since there is birefringence, two linear polarization rays (e(1) and e(2)) be generated for a given incident light. Here n(e1)>n(e2). Although a second-harmonic beam corresponding to the refractive index n(e1)(e(1)(2 omega) ray) can not be generated in a biaxial crystal in usual conditions , it is observed in biaxial crystal of KTiOPO4, when a low-frequency ac field is applied in the c-axis of the crystal. We measured the intensity of the e(1)(2 omega) ray versus ac field frequency response. It is considered that this effect is induced by the quasione-dimensional ionic conductance in KTiOPO4 crystals.
