Optical second harmonic generation (SHG) is the nonlinear conversion of two photons of
frequency «to a single photonof frequency 2co which, in the electric dipole approximation …

THE phenomenon of second-harmonic generation (SHG), whereby a material under
illumination generates light at twice the incident frequency, is finding increasing use in …

The cationic donor–(π-bridge)–acceptor dye, E-4-[(N-alkyl-5, 6, 7, 8-
tetrahydroisoquinolinium-5-ylidene) methyl]-N, N-dibutylaniline octadecyl sulfate is a …

Theoretical expressions for the surface second-harmonic generation are given for some
particular combinations of polarizers. Simulated results are displayed and are compared …

(Z)-α-cyano-β-(N-hexadecylquinolin-4-ylium)-4-styryldicyanomethanide, C16H33–Q3CNQ,
has two Langmuir–Blodgett (LB) phases that differ in thickness, tilt angle and second-order …

This paper is concerned with the second harmonic generation (SHG) from as deposited
layer-by-layer adsorbed films. A nanolayered film was fabricated through the intermolecular …

Direct measurement of the phase of the surface nonlinear susceptibility is based on the
interference of nonlinear optical signals. Up to now, this has not been possible for Second …

stilbazolium dyes and 4, 4'-dioctadecyl-3, 5, 3', 5'-tetramethyldipyrryl-methene hydrobromide …

Second-harmonic generation (SHG) studies have been carried out on Langmuir–Blodgett
films of 2-docosyl-amino-5-nitropyridine that were transferred by two different dip** …

Complexation of a hemicyanine-based amphiphile at the air− water interface by
polyelectrolytes introduced in the aqueous subphase is shown to be a convenient and …
