  We report on a possible optical tuning of the spin Hall conductivity in
mono-layer transition metal dichalcogenides. Light beams of frequencies much
higher than the energy scale of the system (the \textit{off-resonant}
condition) does not excite electrons but rearranges the band structure. The
rearrangement is quantitatively established using the Floquet formalism. For
such a system of mono-layer transition metal dichalcogenides, the spin Hall
conductivity (calculated with the Kubo expression in presence of disorder)
exhibits a drop at higher frequencies and lower intensities. Finally, we
compare the spin Hall conductivity of the higher spin-orbit coupled WSe$_{2} $
to MoS$_{2} $; the spin Hall conductivity of WSe$_{2}$ was found to be larger.
