A new type of compact magnesium cell with room-temperature walls have been developed for high resolution
spectroscopy on the Mg 1S0-3P1 intercombination line. Saturation resonances with a FWHM of 1.3.MHz have been
detected in this cell in the fluorescence signal. The time selection method was applied to eliminate the background signal
caused by the scattering of laser beams on cell windows. The signal-to-background ratio drastically increased by the
spatial localization of excited atoms owing to collisions with atoms of a low-pressure inert gas.
We developed a laser system at 457 nm based on a CW ring Ti:Sap laser and an enhanced cavity SHG in LBO and KN crystals with linewidth < 30 KHz for interferometry experiments with Mg atomic beams. For laser cooling and deflection of a Mg beam, a laser system at 285 nm based on a ring R6G CW dye laser and SHG in BBO nonlinear crystal has been realized. The results of Mg interferometry experiments in four-beam Borde' geometry and the results of Zeeman cooling experiments in a transverse magnetic field are presented. Zero order interference fringes corresponding to the recoil doublet with the resolution of approximately 30 KHz were detected. A Mg beam with a flux of approximately 1011 atoms/s, the mean velocity of approximately 200 m/s, and the width of velocity distribution of approximately 50 m/s (FWHM) have been obtained.
