Power Laser Technology at ISI 2013
Mrňa, Libor
The article described the activities of the ISI laser center. It was advanced diagnostics of laser welding process using frequency analysis, the development of a new type of adaptive mirrors for high power laser applications, an apparatus construction for laser hybrid laser-TIG welding, the development of new types of solar absorbers. Contract research for companies was offered.
New trends in the metrology of geometrical quantities
Lazar, Josef
The contribution deals with an overview of trends in modern fundamental dimensional metrology. This is since the introduction of the definition of metre derived from the vacuum speed of light the domain of laser optics and interferometry. The fundamental etalons of length are highly stable optical oscillators – lasers and the primary measurements of lengths are performed by interferometers. This overview covers the newest results of development of stabilized lasers and interferometry of high resolution in the sub-nanometre range especially concerning the results achieved at the Department of Coherence Optics of the Institute of Scientific Instruments of the ASCR in this field.
