We propose a simple, controllable and highly efficient all-optical guide for a cw cold molecular beam in a blue-detuned parallel hollow beam over a long distance of ∼1 m. The hollow beam is generated by a beam shaper composed of a nonlinear ZnSe crystal. We demonstrate theoretically our optical mole...
