Chirp cooling
Webfrequency is called Zeeman cooling,2 while the correspond-ing technique based on varying the laser frequency is called chirp cooling.3–6In both techniques the laser is detuned to be below the zero-velocity resonance frequency of the moving atom. The detuning is chosen to be such that the atoms mov- http://atomcool.rice.edu/static/bradley_hulet_1996.pdf
