One dimensional magneto-optical compression of a cold CaF molecular beam

ORAL

Abstract

We demonstrate one dimensional, transverse magneto-optical compression of a cold beam of calcium monofluoride (CaF). By continually alternating the magnetic field direction and laser polarizations of the magneto-optical force (RF-MOT), a photon scattering rate of 2$\pi $ x 0.4 MHz is achieved. A 3D model for this RF-MOT, validated by agreement with data, predicts a 3D RF-MOT capture velocity for CaF of 5 m/s.
