Abstract | We demonstrate a Magneto-Optical Trap (MOT) configuration which employs optical forces due to light scattering between electronically excited states of the atom. With the standard MOT laser beams propagating along the \{$\backslash$it x\}- and \{$\backslash$it y\}- directions, the laser beams along the \{$\backslash$it z\}-direction are at a different wavelength that couples two sets of \{$\backslash$it excited\} states. We demonstrate efficient cooling and trapping of cesium atoms in a vapor cell and sub-Doppler cooling on both the red and blue sides of the two-photon resonance. The technique demonstrated in this work may have applications in background-free detection of trapped atoms, and in assisting laser-cooling and trapping of certain atomic species that require cooling lasers at inconvenient wavelengths. |
