in the answer ID: 1009023201.Ph it is states that "The efficiency of these 
laser-cooling systems is based on the cooling efficiency relative to the 
absorbed laser power.  Reports on this efficiency range from approximately 0.5% 
to 2.0%".  Is the efficiency equal to the doppler shift which determines the 
amount of kinetic energy that is turned into light?  Is all of the laser 
energy absorbed?  where does all of the lost energy go too?  why is this such 
an inefficient process?
