Thanks for the question.  I think you were reading about an experiment that 
created a material called a Bose-Einstein condensate.  This can only exist at 
very low temperatures, and the laser beams are used in a special way to cool the 
condensate.  The condesate has the properties of slowing down light tremendously 
and also not absorbing the light.  One place you can read about this is at:
