Studium plazmatu během pulsní laserové depozice kompozitních vrstev nanokrystalického diamantu/amorfního uhlíku a jejich strukturní vlastnosti
Novotný, Michal ; Jelínek, Miroslav ; Bulíř, Jiří ; Vorlíček, Vladimír ; Mosnier, J.-P. ; Duclére, J.-R. ; Popov, C.
Nanocrystalline diamond/amorphous carbon composite thin films were prepared by hybrid technique combining pulsed laser deposition with a capacitively coupled radiofrequency discharge. Optical emission spectroscopy was performed for plasma monitoring during the deposition process.
Řádkový CCD sensor ILX511 pro fyzikální měření
Bartoněk, L. ; Keprt, Jiří
The practical use of the CCD linear image sensor ILX511 for scanning of light in some optical applications (spectroscopy) is presented. Communication of the equipment (CCD linear image sensor) with computer is realized with the help of parallel interface of a personal computer (PC) without additive interface card. The use of the linear detector is presented in the case of detection of the optical spectrum of the mercury lamp.
Využití počítače při optickém měření nárůstu pneumatik během volné rotace
Bartoněk, L. ; Keprt, Jiří
The presented method is based on utilization of optical trace of luminous slot on tyre profile. This optical trace enables the measurement of tyres growth at free rotation during low and high revolution. It is one of tests in sense of regulation of U.N. Commitee for homologation of motorcycle tyres.
Příprava čerpacího svazku pro metodu OPCPA v laboratoři SOFIA
Dostál, Jan ; Kuhnová, Gabriela ; Turčičová, Hana
The OPCPA technique is currently one of the most perspective method of the amplification of ultrashort laser pulses. In our case, the pump beam for the OPCPA process will be realized as 3ω from the hybrid iodine photodissociation laser system SOFIA.
Experimental results on chemical generation of atomic iodine
Špalek, Otomar ; Jirásek, Vít ; Čenský, Miroslav ; Kodymová, Jarmila ; Jakubec, Ivo
In this paper were presented experimental results on chemical generation of atomic iodine.
Generation of atomic iodine for chemical oxygen-iodine laser
Jirásek, Vít ; Špalek, Otomar ; Kodymová, Jarmila ; Čenský, Miroslav
A new method of atomic iodine generation for chemical oxygen-iodine laser based on fast reactions of gaseous reactants.
Research and development of chemical oxygen-iodine laser in the Institute of Physics Academy of Science of the Czech Republic
Čenský, Miroslav ; Kodymová, Jarmila ; Špalek, Otomar ; Jirásek, Vít
Chemical Oxygen-Iodine Laser and Prague Asterix Laser System are two iodine lasers studied in the Institute of Physics in Prague. Survey of the research made on the first system in this institute is given in this presentation.
Hybrid laser chain SOFIA at the Institute of Physics AS CR
Turčičová, Hana ; Straka, Petr ; Skála, Jiří ; Králiková, Božena ; Rohlena, Karel ; Ullschmied, Jiří ; Jungwirth, Karel
SOFIA is a hybrid laser chain where the laser beam generated in a solid state oscillator is amplified in a gas medium of iodine photodissociation amplifiers.SOFIA project is realized to speed up the modernization of the laser system PALS by the OPCPA method.
Laser cladding with a numerical modelling of the temperature field in material utilization
Stranyánek, Martin ; Chmelíčková, Hana
Laser cladding is presented as a one of the technologies of laser material surface treatment. A series of speciments have been treated using CO.sub.2./sub. laser with a maximum output power of 2.5 kW by this technology. Some characteristics and properties such as shape or microhardness of clad layers were analysed. For numerical calculations of the laser induced temperature field in treated material was used the finite difference method.
