Description:
Light is not only a subject of measurement but can be a very useful tool for measuring. It plays a dominant role in the measurement of dimensional quantities. Coherent light from a highly stable laser source is represented by a precise wavelength which can be seen as an elementary etalon of length. Metrology of length is in fact metrology of optical frequencies and a broad family of interferometric techniques converting a precise wavelength into the measurement of real objects. The precision (stability) of the best optical oscillators are now close to overcoming the stability of an atomic clock. This, with help of femtosecond optical frequency synthesis, will most likely lead to unification of standards of time and length into one precise laser, called an optical clock. and Josef Lazar a kolektiv oddělení koherenční optiky.

Description:
Nanobiophotonics is one of the most recent interdisciplinary scientific disciplines that originated at the frontiers of nanotechnology, photonics and biomedical sciences. The aim of nanobiophotonics is to transfer the medical diagnostics and therapy to the level of individual proteins and biologically active molecules, acting as cornerstones of the living cell. One of the key roles in its advancement can be attributed to the development of ultrafast pused lasers. These allowed to cross-combine spectroscopic, imaging and time-resolved methods and provide complex, multi-modal information about biological structures and phenomena on the nanometer scale. In our contribution we give an overview of the most important moments mapping the path from the discovery of the first laser to the current state of nanobiophotonic technologies in the world, and perspectives of this new scientific field in Slovakia., Nanobiofotonika je jedným z najmladších interdisciplinárnych vedeckých smerov, ktorý vznikol na pomedzí nanotechnológií, fotoniky a biomedicínskych vied s cieľom preniesť medicínsku diagnostiku a terapiu na úroveň proteínov a biologicky aktívnych molekúl - základných jednotiek živej bunky. Kľúčovú úlohu v jeho rozvoji má predovšetkým vývoj pulzných laserov s ultrakrátkymi impulzmi, ktoré umožnili prepojiť spektroskopické, zobrazovacie a časovo rozlíšené metódy a poskytujú dnes komplexnú multimodálnu informáciu o biologických štruktúrach a javoch na nanometrovej škále. V našom príspevku uvádzame prehľad vybraných významných momentov mapujúcich cestu od objavenia prvého lasera cez súčasny stav nanobiofotonických technológií k perspektívam tejto novej vednej oblasti na Slovensku., Dušan Chorvát ml., Alžbeta Chorvátová., and Obsahuje bibliografii

Description:
We have proposed a probabilistic quantum amplifier, which is capable of amplifyzing weak light signals in such a way that phase of the light is not only preserved, but its resolution is improved as well! Surprisingly, this "noise-free" amplification is achieved by addition of incoherent thermal noise followed by a photon subtraction scheme. The amplifier, which has been already experimentally implemented, might in the future become a valuable tool for quantum metrology of quantum communication., Petr Marek, Radim Filip., and Obsahuje bibliografii

Description:
Low-level laser therapy belongs to a group of interactions of laser radiation with living tissues and cells. The exact underlying mechanism of action at the molecular level as well as the exact relationships between laser radiation parameters (Wavelength, intensity, and dose) and wound healing process are still not known. In this review basic principals of low-level laser therapy from laser beam origin through radiation interaction with tissues to experimental and clinical studies are discussed., Martina Poláková, Róbert Kilík, Peter Gál., and Obsahuje bibliografii

Description:
An essential part of the ESFRI roadmap to foster the European science in the field of large laser systems, the project ELI-Beamlines is to be built in the Czech Republic. The project has been submitted by the Institute of Physics to the European Commision and it is expected to be financed from the structural funds just due. The facility, which consists of several laser beamlines delivering a very high power density (up to 1023 W/cm2) on the target in a repetitive regime, should be ready by 2015. A smaller sister-project HiLASE should support the ELI-Beamlines by providing high average power repetitive ns lasers as an intermediate pumping element of the ELI laser chains, but, at the same time, of interest for various laser assisted technologies. and Karel Rohlena.
