Laser Excitation of Optical Spectra
A brief description is given of the characteristics and types of lasers available. The use of lasers for the excitation of molecular spectra, especially resonance fluorescence spectra, is illustrated with examples. The technique of saturation spectroscopy, or “inverse Lamb-dip” spectroscopy, as a means for achieving ultrahigh resolution is discussed. The application of high-powered lasers to the observation of two-photon spectra, both with and without Doppler broadening, is also discussed.
