        | "There are other possibilities; for example, an 'air laser' sensing technology developed at Princeton may be able to remotely measure airborne environmental pollutants and greenhouse gasses.
 
 
  
(Air Laser) 
The image shows a pulse of infra-red light 
from this "air laser." The center region 
represents the highest intensity; 
the outer areas have lower intensity light.  
The technique could be used for sensing  
minute quantities of gas in the air from a distance.

Also, take a look at this dual-laser sensing system  under development at the Department of Energy's Oak Ridge National Laboratory.
