The magneto-optical trap provides preliminary cooling of the ensemble of atoms to produce Bose-Einstein condensates and degenerated Fermi gases, for precision spectroscopy and frequency standards based on an atomic fountain. Despite considerable progress in cooling atomic gases, the problem of cooling ensembles of complex particles remains urgent. In this connection, a search is being made for universal cooling methods that do not depend on the internal structure of the particles. The application of the feedback method based on measurement of the Bragg backscatter signal is considered to be promising [J. Phys. B 47, 135303 (2014); JETP Lett. 100, 536 (2014)]. At the stage of developing the method, it is reasonable to use atoms preliminarily cooled in MOT as the test particles. Such application of the Magnetooptical trap, which is available in the RC OLMIV, is assumed in Project 11.38.640.2013 in the framework of Activity 2.

February 19, 2015. A meeting of the Users Club of Horiba Jobin Yvon Raman spectrometers and fluorimeters was held in the RC "Optical and laser materials research". The company Horiba Jobin Yvon was represented by Emmanuel Froigneux and Reynald Hurteaux, and the company "Nytek Instruments", the exclusive supplier of Horiba Jobin Yvon products in the Russian Federation - Mikhail Trusov and Anna Nazarova. The meeting was attended by specialists from resource centers "Optical and laser materials research", "Geomodel" and "Chemical analysis and materials research", as well as interested employees of the faculties of Physics and Chemistry. Fruitful discussions were held to discuss new technical solutions in the field of Raman spectrometry and fluorimetry and measurement techniques.
