Hi Phil,

I believe that the energy density (if I may) is inversely 
proportional to the cross sectional area.  Assuming no absorption, 
the total energy flowing thru any cross sectional area will be the 
same as any other area (area being what is occuppied by the beam at 
any point).  So, if a non diverging beam passes thru a focusing lens, 
the energy density will increase as the area of the beam is 
decreased.  If one measures distance from the focal point and 
compares two cross sectional areas within the converging beam, the 
energy density would follow an inverse square law.
