  The recently discovered Orbital Feshbach Resonance (OFR) offers the
possibility of tuning the interaction between alkaline earth(-like) metal atoms
with magnetic field. Here, we introduce a single-manifold Raman scheme to dress
the OFR, which allows us to tune the interaction with the optical field and it
is readily realizable in experiment. We demonstrate the scattering resonance
could be shifted by the dressing Raman laser using few-body and many-body
mean-field calculation, which give rise to an optical dependent two-body bound
state and Raman coupling induced BCS-BEC crossover in the BCS-type mean field
theory. Besides, we also discuss the application of single-manifold Raman
scheme in Kondo research by writing down a Kondo lattice model.
