Optical investigations of the states in GaP:Ni
Journal of Physics C: Solid State Physics, 1982 This paper reports photoconductivity measurements of semi-insulating Ni-doped GaP materials. The photoresponse spectra obtained exhibit strong onsets at 0.62 eV and 0.95 eV, as well as a number of weaker features. Optical transitions are interpreted as between Ni3+ and Ni2+ ions, and the conduction and valence bands, as well as transitions involving a ...

Optical-acoustic effect in laser optics investigations [PDF]
Revue de Physique Appliquée, 1990 Parameters of the acoustic signals (AS) excited in the massive Al, Be and Cu mirrors by TEA CO2- and Nd : glass-laser pulses were investigated. Correlations between the AS parameters and an emergence of different types of laser-induced damage such as evaporation of heat insulated defects, melting and optical breakdown off irradiated surface have been ...
