Abstract
Applicant has discovered a correlation between photography, the laser mechanism, and SERS. It appears that all three effects or phenomena of photography, laser and SERS, originate from a similar mechanism, namely the amplifying factor comes from Einstein coefficients and subsequent description of inverse population--these being the essential building blocks for the aforementioned three phenomena. Accordingly, one aspect of the invention is to utilize the principles of photography in connection with SERS. Another aspect is to utilize the principles of photography in connection with lasers. A still further object is to employ all three fields to achieve the lasing and laser effects described in greater detail below.
