We report the first observation of sub-natural-width dark resonances of enhanced transparency on the D 2 line of potassium, contained in an optical cell with reduced (8mm) dimensions and buffered by 30Torr of Ne. The Potassium vapours are irradiated

The laser frequency dependence of the photon-stimulated desorption (PSD) of Rb atoms from surfaces prepared by adsorption of rubidium vapor on thin films of polydimethylsiloxane (PDMS) was determined at low light intensities and at room temperature t

Experimental examination of the coherent population trapping that can be established on the D and D lines of Rb at a 12 single hyperfine transition using the Zeeman sublevels of the hyperfine states is reported here. The coherent effects have been ex

The coherent population trapping phenomenon in sodium is probed through energy transfer and energy pooling collisions. Quenching of the excited state population (dark resonance) is measured through the detection of the collisional induced fluorescenc

The photoejection of Na and ${\mathrm{Na}}_{2}$ from surfaces prepared by adsorption of sodium vapor on solid films of polydimethylsiloxane (PDMS) of various molecular weights and structures is found to be dependent on light intensity and frequency.

Two experimental techniques for measuring resistivity behaviour of high T c ceramic superconductors in bulk or thin films are described. Particular attention has been given to the development of a four point contact system, easy to use for reliable r

The shift in the equilibrium distribution between reactants and products in the chemical reaction 2Li⇋Li2 that accompanies an optical orientation of the atomic Li spin angular momentum has been observed, and its dependence and degree of atomic orie

A brief introduction is presented related to three different approaches for Coherent Population Trapping (CPT) observation, namely CPT resonance prepared: (i) in degenerate two‐level system, (ii) by coupling pairs of non‐degenerate Zeeman subleve

Magnetic coherence resonance profiles, obtained at magetic field B = O in Hanle configuration were examined for Na and K atoms in different cells: evacuated glass cells and buffered, coated and uncoated. At low laser power for all cells the shape of
