New analytical behavioral model formulations based on the polyharmonic distortion (PHD) model have been successfully used to describe the nonlinear behavior of transistors and circuits.

We consider a single server system with N input flows. We assume that each flow has stationary increments and satisfies a sample path large deviation principle.

We report the characteristics of two-dimensional distributed feedback lasers with organic thin-film gain media.

We have investigated spectral narrowing in solutions of the conducting polymer DOO-PPV and the laser dye Rhodamine 590 in two cases.

The use of energentic beams for processing semiconductors has given rise to new technologies and new concepts in materials science.

Metallic palladium features have been produced by focused laser- and ion beam-induced decomposition of palladium acetate films.

The laser and phosphor host material with nominal composition LaMgAl(11)0(19) is shown to be nonstoichiometric.

SiOx remains the main starting material for obtaining nanocrystalline Si embedded in a SiO2 matrix.

In this paper the physics of the laser interactions for the studies indicated will be introduced.

Since its first demonstration in 1960, the laser has evolved into many different forms. It can be now found in many industries, in the hospital, and even in the supermarket.
