|"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.
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.
