Novel Machine Learning Approaches to Molecular Coherent Control
... excitation D1Σ0+u ← 1Σ0+g ←B3Π0+u ← X1Σ0+g between 600 and 550 nm requires three photons and thus depends on the laser intensity cubed. Because the pulse intensity is highest for transform limited (TL) pulses one therefore expects these to transfer the greatest population from X to D but the experim ...

Abstract: Interference colors result from the reflection of light from a series of neighboring interfaces that are separated by distances comparable with a quarter of the wavelength of light. .Interference colors are common in some adults of Lepidoptera insects. The integument layers producing inter ...

Interferometry
Interferometry is a family of techniques in which waves, usually electromagnetic, are superimposed in order to extract information about the waves. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its applications to chemistry), quantum mechanics, nuclear and particle physics, plasma physics, remote sensing, biomolecular interactions, surface profiling, microfluidics, mechanical stress/strain measurement, and velocimetry.Interferometers are widely used in science and industry for the measurement of small displacements, refractive index changes and surface irregularities. In analytical science, interferometers are used in continuous wave Fourier transform spectroscopy to analyze light containing features of absorption or emission associated with a substance or mixture. An astronomical interferometer consists of two or more separate telescopes that combine their signals, offering a resolution equivalent to that of a telescope of diameter equal to the largest separation between its individual elements.
