We experimentally demonstrate the highest spectral brightness for the pulsed fiber lasers to the best of our knowledge in a compact high power and pulse energy laser system consisting of a DFB laser diode as a master oscillator and a high-power fiber

A new fibre optic sensor suitable for high voltage measurements is introduced. The sensor is based on a double pass configuration of light through a Bi12TiO20 (BTO) photorefractive crystal. To obtain the double pass configuration, a back-reflecting p

We report on a fiber optic voltage sensor with optically controlled sensitivity. The sensor operates at two widely separated wavelengths (633 nm and 976 nm). one of which is a control signal (976 nm). We have demonstrated experinientally the variatio

It is shown that the air-film material reflectance coefficient, and that for the film material- substrate, can be restored from envelopes of the interference pattern in reflectance spectra. Doing so for oblique incidence of light and for two of its p

An approach of ellipsometric measurements both from ambient media and from transparent or weakly absorbing substrate has been proposed to determine optical constants and thickness of anisotropic films. According to this approach the main refractive i
