Tunable Laser Systems new experiments became possible; however, applications of lasers to chemical studies were limited to cases in which there was a coincidence between the absorption spectra and laser output. The availability of continuously tunable lasers has had an immediate impact on chemical applications because i

Laser-Excited Atomic Fluorescence Spectrometry During the 1960s, the laser was developed as a light source and AFS as a spectrometric technique. In 1971, with the advent of commercially available tunable dye lasers, laser-excited atomic fluorescence spectrometry (LEAFS) had its beginning as an analytical method (.). Researchers had been looking

The laser has several specific qualities that can be particularly useful for exciting fluorescence—its high spectral powers can potentially provide low detection limits while its narrow line
