We report the first systematic measurements of the temperature dependence of optically induced birefringence in benzene 2bromo-- anisole 2-methoxybenzaldehyde and 4methoxybenzaldehyde. The optical Kerr constants relative to benzene are found to be: 1. 00 2. 45 5. 21 4. 89 and 4. 91. respectively. The refractive indices and densities of the liquids for the temperatures studied were also determined. From our measurements the molar Kerr constants and the effective molecular anisotropies were calculated as functions of temperature. The mean value of the secondorder optical hyperpolariZa bility have also been found. We draw some conclusions on the molecular interactions in the liquids. T If" LI I IJIJJJ Nonlinear optical effects in liquids are shaped not only by the optical properties of the isolated atoms (molecules) but moreover by their electric properties and mutual interactions. Hence optical birefringence induced by strong laser light also referred to as the Optical Kerr Effect (OEK) is a source of highly relevant information concerning the structure the electrical properties and the optical properties of atoms and molecules including their interactions in dense media. OKE measurements yield the optical Kerr constant which characterized the macroscopic properties of the medium. If carried out versus temperature OKE measurements additionally provide information on the local structure of the medium and 146 / SPIE Vol. 1391 Laser Technology Ill (1990) 0-8194-0458-6/91 /$4. 0
