The kinetics of formation of nanostructured glass-ceramic materials based on silicate glass doped with lead sulfide PbS is investigated using small-angle X-ray scattering and X-ray powder diffraction. The influence of two-stage heat treatment on the

Riphean stromatolitic formations flank the East European epi-Karelian platform only in the east and northeast. They are traceable as long (over 3600 km) relatively narrow belt consisting of two rectilinear segments, one running along the Urals wester

Columnar stromatolites representing more than a half of species described in Precambrian stromatolite assemblages reveal a regular trend of size variations during the Proterozoic and Early Paleozoic. Their dimensional parameters grew gradually during

The use of PbS quantum-dot-doped glass as an intracavity saturable absorber for passive mode locking of a Cr4+:YAG laser was investigated. We obtained 10 ps pulses at a repetition rate of 235 MHz with an average output power of 35 mW. This mode-locke

Nonlinear optical properties of phosphate and silicate glasses doped with PbS and PbSe quantum dots of different sizes were studied. Absorption saturation intensity in the range of the first and second excitonic transitions was estimated. Passive Q-s

In this paper, we present a silicate glass doped with PbS-quantum dots (QDs) as new saturable absorber (SA) for Q-switching of a diode-pumped Nd:YVO/sub 4/ laser. Q-switched pulse width of the laser with the PbS-QDs-doped silicate glass SA was measur

In this presentation we report results when PbS QD-doped glass has been implemented as a saturable absorber for the passive mode-locking of a cw Cr:YAG laser. The tuning range covered optical communication wavelengths around 1500 nm.
