Physical properties of Al-doped GaSe or GaSe:Al(0.01, 0.02, 0.05, 0.1, 0.5, 1, 2 wt%) crystals in charge composition were studied in comparison with pure GaSe to reveal the potentials for sub- and microwave elec-trooptical application. Aluminium was not detected in GaSe:Al by X-ray chemical analysis. It was found that resistivity of GaSe:Al drastically increases with Al doping up to 105-107 in comparison...
The near IR and sub-microwave range optical properties of AgGaS2-doped GaSe (GaSe:AgGaS2) grown in accordance with chemical formula [2(GaSe)]1-x:(AgGaS2)x, x=0.1, in charge composition, were studied in comparison with that in 2 wt% and 10.2 wt% S-doped GaSe (GaSe:S) to reveal the potentials for phase matching and frequency conversion from near IR into sub-microwave range by down-conversion of fs Ti:Sapphire...
GaSe1-xSx single crystals has been grown by Bridgman-Stockbarger technique. Structural quality has been evaluated with TEM observation. Terahertz time-domain spectroscopy has been applied for measurements of the frequency-dependent optical constant of doped GaSe crystals as a function of s-content.
For prospective nonlinear crystals GaSe1-xSx experimental study of second harmonic generation processes of Er3+:YSGG-, CO2- and CO-lasers has been performed, control experiment on difference frequency generation of two lines of CO2-laser has been realized, the transmission spectra and dispersion of complex refractive indices in terahertz range have been measured.
