Abstract
In a system and method for generating second order nonlinear optical effects and in particular second order harmonic radiation (SHG), a beam of light is transmitted through and/or reflected from a substance which includes both at least one species selected from amorphous and glassy organic materials and at least one species of hyperpolarizable component, and which is in xy planar film or coating form or in light-transmissive 3-dimensional form and which substance is preferably subjected to a polarizing electric field, such that (a) when the substance is in the form of an xy planar film or coating, the field is applied in the plane of the film and the beam of light is caused to impinge thereon at angle other than normal to the xy plane, (b) when the substance is in 3-dimensional form, the field is applied along a line (an arbitrary x-axis) and the beam of light includes components polarized along at least one of the y- and z-axes; and (c) emergent SHG, which includes at least one component which is polarized perpendicular to the direction of polarization induced by the electric field in the hyperpolarizable component(s), is detected, observed, measured and/or utilized.
