The parametric optimization of the Ne–CuBr UV laser excited by longitudinal pulsed discharge is analysed by using a self-consistent kinetic model. Consistent characteristics of the optimization process are obtained by comparing with the experimenta

Interference of light has been reinvestigated theoretically by linear superposition of two different state-vector functions, of which each describes the photons from one of two different light sources in both polarization and intensity. By the use of

By using one-dimensional photon state-vector function obtained previously, a general analytic expression is deduced for the optical two-hole interference experiment, which not only greatly enlarges the range of the observable, but also completely rep
