I was hoping to contrast stimulated emission<http://en.wikipedia.org/wiki/Stimulated_emission>vs spontaneous emission <http://en.wikipedia.org/wiki/Spontaneous_emission> with respect to entropy.
Note I'm not here talking about concentrating energy in a material (the material as a whole goes to a lower energy state), but in a field: "photon created in this [stimulated emission -- JAB] manner has the same phase<http://en.wikipedia.org/wiki/Phase_(waves)> , frequency <http://en.wikipedia.org/wiki/Frequency>, polarization<http://en.wikipedia.org/wiki/Polarization_(waves)>, and direction <http://en.wikipedia.org/wiki/Direction_(geometry)> of travel as the photons of the incident wave". This has the surface appearance of spontaneous order. On Fri, May 17, 2013 at 11:55 AM, Edmund Storms <[email protected]>wrote: > Understanding the word "spontaneous" is essential.
