The first example of laser cooling, and also still the most common method (so much so that it is still often referred to simply as 'laser cooling') is Doppler cooling. Doppler cooling, which is usually accompanied by a magnetic trapping force to give a magneto-optical trap, is by far the most common method of laser coolin… WebIn this video, we look at some of the key physics behind a handful of techniques that can drive atoms to incredibly cold temperatures using nothing but light.

WebStill, there are two significant problems with the chirp slowing technique: (1) It may be technically difficult to sweep the frequency by the amount necessary to cool a significant portion of the velocity distribution, and (2) the atoms do not all arrive at their final velocity at the same longitudinal location. WebApr 1, 1999 · Experimental results on narrow line cooling of strontium atoms are presented. Doppler cooling is performed on the /sup 1/S/sub 0/-/sup 3/P/sub 1/ intercombination transition at 689 nm resulting in temperatures near the recoil limit in a one-dimensional (1-D) optical molasses.
