    Notes: Abstract The first investigations on the laser-induced reduction of YBa2Cu3O7−x are presented. Here, the oxygen content of the material is diminished by local heating under cw Kr+ laser irradiation in H2 atmosphere. The technique permits the superconducting properties of the material to be locally changed or destroyed. Laser-induced surface metallization may be useful for the electroding of such materials.

    Notes: Abstract Investigations on the laser-induced oxidation of YBa2Cu3O6 are presented. Here, the oxygen content of the material is locally increased by laser-induced heating under cw Ar+ or Kr+ laser irradiation in 02 atmosphere. The technique permits direct-writing of superconducting patterns into the semiconducting sample surface.

    Notes: Linear dichroism and second-harmonic generation (SHG) have been measured in Langmuir-Blodgett (LB) multilayers of Z-type structure of amphiphilic indandione-1,3 pyridinium betaine (IPB) with an aliphatic tail containing 17 carbon atoms (C17IPB). The dichroic ratio As/Ap of electronic absorption of s- and p-polarised light and the SHG intensity show that the ‘heads’ of C17IPB molecules are predominantly oriented along the deposition direction of monolayers on a quartz substrate. Orientation parameters and mean statistical azimuthal and tilt angles are evaluated as a function of the number of monolayers. The SHG efficiency has been measured in C17IPB monolayers on a water surface as a function of surface pressure. The effective hyperpolarisability β of the IPB molecule has been determined experimentally in a chloroform solution by the hyper-Rayleigh-scattering method. The obtained value of β = (138 ± 16) × 10-30 esu is in good agreement with theoretical estimates.
