Laser absorption spectrometry — (LAS) refers to techniques that utilize lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS).It is well known that optical spectroscopic techniques in general and laser based techniques in… … Wikipedia
Laser pumping — is the act of energy transfer from an external source into the gain medium of a laser. The energy is absorbed in the medium, producing excited states in its atoms. When the number of particles in one excited state exceeds the number of particles… … Wikipedia
