Second-harmonic generation in quinquethienyl monolayers
Physical Review B, 1988Well-organized monolayers of quinquethienyl (QT) have been studied by second-harmonic generation (SHG). Due to the properties of the molecular hyperpolarizability tensor ${\ensuremath{\alpha}}^{(2)}$ of QT, SHG signals originating from the direction of the surface normal, which corresponds also to the alignment direction of these molecules of rodlike ...

Second-harmonic generation imaging of cancer
2014The last 30 years has seen great advances in optical microscopy with the introduction of sophisticated fluorescence-based imaging methods such as confocal and multiphoton laser scanning microscopy. There is increasing interest in using these methods to quantitatively examine sources of intrinsic biological contrast including autofluorescent endogenous ...

Oscillations and quantized second-harmonic generation
Physical Review A, 1988We investigate quantum-mechanical second-harmonic generation for parameters such that classical electrodynamics predicts oscillations. Specifically we calculate the Q distribution function in a Gaussian approximation about the classical limit cycle. In the classical limit initial rapid collapse of the Q distribution into the neighborhood of the limit ...
