<Laser detuning> is the difference between a <laser> <angular frequency> and a specified atomic resonance <angular frequency>. Red detuning has $\delta<0$; blue detuning has $\delta>0$. The sign matters in <laser cooling>: a moving atom can see a red-detuned <laser> closer to resonance because of the <Doppler effect>.
