Abstract
A new generation of spectroscopic tools have emerged with such extremely high resolution capabilities that we are no longer limited by the so called "instrumental linewidth." In today's optical spectroscopy, the limit is more likely to be the natural or, in certain cases, the transit-time linewidth. To perform ultrahigh resolution spectroscopy one generally requires a tunable laser with a narrow spectral width, a means of reducing any mechanism that tends to broaden the spectral line under observation (e.g., Doppler and collisional broadening) and, finally, a precise method of calibrating the tuning range of the laser. This paper presents a brief review of the various techniques used to achieve high resolution spectroscopy with lasers.
