Laser detuning refers to the difference in frequency between a laser light and a specific transition frequency of an atom, molecule, or other system. In the context of atomic or molecular physics, this concept is often encountered when discussing laser cooling, optical pumping, or coherent control experiments. ### Key Aspects of Laser Detuning: 1. **Definition**: - It is the frequency offset of the laser light from the resonance frequency of the atomic transition.
