It is demonstrated that the use of Selective Reflection process obtained with the help of a thin cells filled with the Cs atomic vapor allows one to detect seven Fg=3 → Fe=5 atomic transitions in an external magnetic field in the range of 0.5–3 kG.
Planar arrays of silver nanoparticles covered by thin layers of organic dye molecules or semiconductor quantum dots are investigated from the point of view of electrodynamics interactions between the constituents of the composite films.
Abstract: Nonlinear optical response of a thin layer of rarefied atomic vapor is examined by taking into account the atomic motion as well as collisions with the cell walls. Extraordinary pattern of self-diffraction spectrum due to the transient polarization is predicted. It is shown that the spectra are Doppler free and depend strongly upon the vapor thickness. A new possibility of signal enhancement...
The influence of oxygen exposure on the mechanism of photoinduced desorption from metal surfaces and its modification has been studied. For this purpose small Na particles adsorbed on single-crystal quartz substrates served as amodel system. They were prepared under ultrahigh vacuum conditions by deposition of Na atoms and exposed to laser pulses with =532nm and of 7ns duration. In addition to atoms,...
