2016 - Czech
Smluvní výzkum byl zaměřen na přípravu a optimalizaci procesu plazmatické depozice vybraných tenkých vrstev kovů a polovodivých oxidů s požadovanými optickými vlastnostmi. Cílem bylo připravit průhledné barevné electrochromické vrstvy na teplotně citlivé substráty, vrstvy s vysokým indexem lomu na lisované plastové struktury a lesklé kovové vrstvy na porézní keramické masky.\n Contract research was focused on preparation and optimization of the plasma deposition process of selected thin metal and semiconducting oxide layers with required optical properties. The goal was to prepare transparent color electrochromic films on thermally sensitive substrates, the layers with high refractive index on the surface of pressed plastic structures and shiny metallic films on the porous ceramic masks.\n

AlSb/InAsSb/AlSb deep QWs for the two band high temperature superlinear luminescence
Hulicius, Eduard; Hospodková, Alice; Pangrác, Jiří; Mikhailova, M.
2015 - English
InAlAsSb/GaSb based hetero-nanostructures with deep quantum wells grown on GaSb are promising materials for the optoelectronic devices for near- and mid-IR spectral regions. Optical power and quantum efficiency of the LEDs based on the narrow bandgap semiconductor compounds (InGa)(AsSb) are limited by the nonradiative Auger recombination. Earlier we have proposed a method to increase the optical power in the bulk narrow bandgap and later in GaSb-based nanostructures with a deep QW by the effect of impact ionization on the QW with high band offset.

BRK Technologies s.r.o. - Laser incineration of toxic medical wastes: towards to 100% safety
Rostohar, Danijela; Bulgakova, Nadezhda M.; Flimelová, Miroslava
2015 - English
The aim of the project is to design, construct and optimize a prototype of a laser incineration chamber (LICh) for treatment of toxic medical wastes. The LICh must provide safe incineration of organic wastes by an intense laser beam generating very high temperature of the incineration process. The LICh and involved technology must be relatively cheap and mobile for easy installation near the medical institutions producing toxic wastes. The most important aspect is the control of incineration products to ensure 100% safety of the gases issuing into atmosphere from the LICh. This is the first step of the whole project with aim to do the state of the art study and propose next steps.

Investigation of thermal depolarization in high-power TGG ceramic rods
Lucianetti, Antonio
2015 - English
Wavefront deformation and thermal stress birefringence were evaluated for high-power TGG ceramic rods. The real laser beam profile used to heat the TGG ceramics was considered in the calculations. The numerical model was bench-marked with experimental data at about 100 W and then used to study the scalability of a similar TGG-based optical isolator up to 1 kW average power.

Labio, a.s. – studie možností rozšíření plynového chromatografu
Divoký, Martin
2015 - Czech
Projekt byl zaměřen na testování a vývoj UV plynového chromatografu Labio G11. Spektrometr chromatografu byl modifikován, aby došlo k rychlejšímu propláchnutí vnitřního prostoru dusíkem (neabsorbuje v UV) a byla uspíšena připravenost k provozu. Dále byla otestována citlivost spektrometru v UV pod 150 nm a navrženy možnosti rozšíření citlivosti v této oblasti. This project aimed at testing and development of a UV gas chromatograph Labio G11. A spectrometer from the chromatograph was modified in order to increase nitrogen gas flow in the device and speed at which the inner of the spectrometer is filled with nitrogen (that doesn’t absorb in UV). This allowed decreasing startup time of the spectrometer. Additionally, sensitivity of the spectrometer in region below 150 nm was tested and ways to increase this sensitivity were proposed.
