  Heteronuclear alkali-metal dimers represent the class of molecules of choice
for creating samples of ultracold molecules exhibiting an intrinsic large
permanent electric dipole moment. Among them, the KCs molecule, with a
permanent dipole moment of 1.92~Debye still remains to be observed in ultracold
conditions. Based on spectroscopic studies available in the literature
completed by accurate quantum chemistry calculations, we propose several
optical coherent schemes to create ultracold bosonic and fermionic KCs
molecules in their absolute rovibrational ground level, starting from a weakly
bound level of their electronic ground state manifold. The processes rely on
the existence of convenient electronically excited states allowing an efficient
stimulated Raman adiabatic transfer of the level population.
