Part of the experimental setup for cooling (slowing) and trapping of rubidium atoms. Two diode lasers with Littrow resonators are seen in the foreground. In the next part of the optical table there are components used to control frequency, intensity and polarization of the laser beams (lenses, mirrors, waveplates, acousto-optic modulators, diaphragms, polarizers and others). In the background there is a vacuum setup, where atoms are trapped.
