FIG. 1.

Sketch of the experimental setup for QNLO (and LO) measurements. Two types of acquisitions in transmission and/or reflection are possible: (1) the theta scan where the incident angle is modified at a fixed incident polarization (classical Maker-fringes recording); (2) the psi scan where the incident polarization is modified, by rotating a half-wave plate, at a fixed angle of incidence .

FIG. 2.

LO reflection measurements on a GeOS film at 1064 and . (Left) Circles are experimental data and solid lines correspond to the best optical model. For comparison purposes, the calculated pattern without interference terms for the two layers (dotted line) is reported at . For clarity, the reflected pattern at is vertically shifted. (Right) Scheme of the thin film and best set of optical parameters for the two layers of GeOS.

FIG. 3.

SHG (top) and (bottom) transmitted signals in -type LB films. Theoretical SHG patterns as a function of the substrate thickness: (Left) ; (right) . Full lines correspond to LB films with thicknesses (circle) and (crosses) coated on one side of the substrate. Dotted lines correspond to LB films with thickness coated on both sides of the substrate.

SHG of a left -quartz plate with horizontal -axis . Experimental (symbols, dotted lines) and calculated (solid lines) transmitted and reflected signals: (left) including the transmitted bound-wave terms ; (right) including both the transmitted and reflected bound-wave terms and . Absolute intensities are in arbitrary units.

FIG. 6.

SHG of a left -quartz plate with vertical -axis . Experimental (symbols) transmitted (left) and (right) SHG Maker fringes. Solid lines are calculated patterns including LO gyrotropic effect. Dotted lines are calculated patterns with no LO gyrotropic effect. Intensities are in arbitrary units.

FIG. 7.

Linear optical rotatory dispersion (L-ORD) of left -quartz. Solid lines are only indicative. Vertical dashed lines point out data from this work (cf. Table II); other values are taken from litterature (Refs. 3 and 43).

Effects of SHG magnetic-dipole terms (; ) in KDP. Experimental (symbols, dotted lines) transmitted polarized SHG signals of a [110] KDP plate with horizontal -axis, 45°- (left) and (right), respectively. Solid lines are calculated patterns with electric-dipole terms. Dashed lines are calculated patterns with electric-dipole terms and magnetic-dipole terms ( and ). Intensities are in arbitrary units.
