An analysis of two-photon interaction was carried out for a two-level system with mixed states parity. Janes-Cummings-type semiclassical equations have been derived for this model and their computer solutions have been analysed; an approximate expres

Photonics in Switching.
Nonlinear optical materials are essential components of functional photonic devices for optical communications, in particular, all-optical switching devices. Nonlinear switching devices can be based on optical waveguide structures which provide stron

Cleaning treatments necessary for stone conservation consist of removing compounds that were superimposed on the original material by means of physico-chemical processes.,The purpose of this work is to identify the transformation of stone surface by

Calibrated spectral measurements of the light emitted by a pulsed high-pressure mercury capillary lamp are presented. These pulsed lamps have been used in a previous work to pump a Rhodamine 6G laser. The measurements presented here show a very high

This paper discusses the possibilities of pulsed high pressure mercury capillary lamps as efficient pumping sources for dye lasers. Spectral measurements show that a spectral efficiency as high as 24 per cent may be reached for a typical blue lasing

The optimum coupling for dye lasers has been theoretically studied, taking into account the correct rate equations. The results obtained are applicable also to flashlamppumped dye lasers, provided that the duration of the pumping pulse is long compar
