Based on the theory of weak localization, taking into account the mechanism of spin-orbit scattering, thepatterns of change in the magnetic conductivity of films PbSnAgTe are considered. The dependences of themagnetoresistance of PbSnAgTe films in ma

Mechanisms of a change in the refractive index appearing in an intensely diode-pumped Yb:YAG-laser disk element are studied with the help of polarisation interferometry and dynamic grating testing. It is found that changes in the electronic component

2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC).
Strong refractive index changes (RICs) of electronic origin (due to polarizability differences in the excited and unexcited activator ions) have been experimentally and theoretically studied recently in the case of the laser crystals and glasses dope

Conference on Lasers and Electro-Optics 2010.
The refractive index changes which can be induced in pumped Nd3+ and Yb3+ doped laser materials have been measured using two pump-probe techniques. Transient signal analysis allows to discriminate electronic and thermal contributions.

The contrast inversion of a DFWM-conjugate wave which is realised by a π-shift of its zeroth harmonic with respect to the remainders has been first investigated. The experimental results for a one-dimensional object and computer-calculated data for
