The history of lasers at the Institute of Scientific Instruments of the ASCR in Brno (ISI) has begun 1249 days after the worldwide premiere of laser. The first to be put into operation at ISI was the He-Ne laser (16 October 1963). Highest attention was then paid to its further development making possible a large number of its applications. The He-Ne laser was followed by a ruby laser (4 March 1964), He-Cd laser (1970), and Nd:YAG laser (1973). The article presents all achievements concerning lasers at ISI accompanied by historic photos, their applications and routes to production at national companies. Nowadays many of these instruments and techniques are in use and are further being perfected, such as interferometric distance measurements with sub-nanometer resolution, methods of comparison of metrological etalons by femtosecond lasers, utilization of laser light for manipulations with micro-object combined with laser micro-spectroscopy., P.

The article describes fundamental and application results obtained in the Department of Quantum Electronics of the Institute of Radio-Engineering and Electronics (IRE) of Czechoslovak Academy of Sciences in Prague. The early success in detection of the Doppler effect of radiation reflected from the first satellite orbiting the Earth - Sputnik (1957) was in the Department followed by systematic work in the area of ammonia masers, both 14NH3 and 15NH3 (1963-72). Short information is given on the first graduate courses in quantum electronics (1963-64) organized by the Department. Department's program of laser development and applications is discussed in details. The results of four key research projects are reported in the article, i.e., (a) ruby laser and its application in ophthalmology (including the first laser surgery of retina carried out in our laboratory), (b) carbon dioxide IR lasers, (c) UV-Vis gas lasers (blue He-Cd laser, near-ultraviolet nitrogen laser), and (d) tunable dye lasers. Unfortunately, the politically motivated dissolution of the Department in early seventies ended all the promising programs., Jan Blabla, Viktor Trkal., Obsahuje bibliografii, and V anglickém názvu uvedeno chybně Quatum - správně = Quantum
The article considers the writings of the sculptor Andreas Schweigl (1735-1812) and the painters Ignaz Chambrez (1758-1842) and Josef Heřman Agapit Gallaš (1756-1840). Around the year 1800, these three Moravian artists recorded their thoughts and insights in a number of texts that variously combined the traditional literary genre of artist’s biography with artistic topography, art criticism and a historical interpretation of early Moravian art and culture. Since all three were in some way connected with the new system of art education, the aim of this study is to examine whether and in what way standardized education affected not only their professional careers, but also their thinking. For all three, that thinking was rooted in a historical interpretation of the early art and culture of Moravia. All three discuss the function of art, artistic ideals, and to some extent the concept of the creative genius, as well as reflecting, directly or indirectly, on the theme of decadence as one stage in the cyclical view of history, in line with the paradigm of the age. The author sets out to compare their texts and in general terms show 1) how artists themselves viewed the importance of art education at the end of the 18 century; 2) how they responded to the changing role of the artist in society; and 3) how they defined artistic ideals and the artist’s social purpose. It is the wider implications of these changes in the artist’s social status, and in the function of art in Moravia and Central Europe generally, that form the primary focus of this study., Pavel Suchánek., and Obsahuje bibliografické odkazy
