Abstract
The deceleration and bunching of cold molecules in a pulsed traveling optical lattice was investigated. A lattice velocity equal to half the supersonic beam velocity and optimum pulse durations helped in decelerating the cold molecule to zero velocity. The large difference of polarizability to mass ratio between the buffer gas and the CO molecules in the pulsed jet led to the preclusion of the buffer gas from the fraction of stationary molecules. The results indicated that the spatial bunching in the optical lattice is induced and the position of the bunch within the lattice can be chosen by varying the lattice velocity.
