Laser spectroscopies have developed along with the lasers used as light sources and may be applied in diverse situations. Techniques and approaches that generally involve a linear response to laser radiation are covered. These are divided broadly into direct and proxy techniques. The former detects the absorption of radiation directly, whereas the latter detects a side effect of absorption such as fluorescence or heating. A selection of the methods outlined are cavity ring-down spectroscopy and its variants, laser-induced fluorescence, photoacoustic spectroscopy, and some double-resonance techniques. The range of topics covered is not intended to be exhaustive and the selection probably indicates the direct experience of the author.
