Laser slowing of CaF molecules to near the capture velocity of a molecular MOT
Laser slowing of CaF molecules down to the capture velocity of a magneto optical trap (MOT) for molecules is achieved. Starting from a two stage buffer gas beam source, we apply frequency broadened "white light" slowing and observe approximately 6x10^4 CaF molecules with velocities near 10\,m/s. CaF is a candidate for collisional studies in the mK regime. This work represents a significant step towards magneto optical trapping of CaF.
