Research output: Contribution to conferencePaperpeer-review


A magnetooptical trap (MOT) for Cr atoms was constructed. The MOT is supplied with atoms in either of two ways. For simple trap diagnostics, a vapor of Cr atoms is generated by resistively heating a Cr-electroplated W filament. Maximum trap loading is provided by producing an atomic beam with a high-temperature oven and then decelerating the atoms by a frequency-chirped laser beam. The trapping laser light and the slowing laser light are produced by separate dye laser systems. Optical leak effects are eliminate by repumping the atoms out of the 5D3 and 5D4 levels using two diode lasers.
