Rövid kivonat:

There is nothing so useful as good theory. As a case in point, the 
compelling need for standoff detection of hazardous gases and vapor 
indicators of explosives has motivated the development of remotely pumped, 
scheme(s) which produce radiation in the backward direction [1,2]. Moving 
from conceptualization to theoretical analysis and experimental 
verification, we demonstrate that high gain can be achieved in air. Backward 
air lasing provides possibilities for remote detection [3] as will be 
discussed.

In related work, the study of quantum coherence effects has lead to 
improvements in laser spectroscopy which allow us to “instantaneously” 
detect anthrax type endospores [4,5].  In the latter example, marker 
molecules in the endospore are put into maximal oscillation which is 
detected by scattering laser light off the coherently oscillating molecules. 
This is called coherent Raman scattering and is a type of Dicke 
superradiance. The preceding topics were tempered and advanced in the heat 
of vigorous debate.
