Saturated Absorption Spectroscopy with Applications to the 3.39 μm Methane Transition

  • J. L. Hall


In basic research we are grateful to be able to pursue research in profitable directions, e.g., those directions where the boundaries of experimental or theoretical possibilities seem most susceptible to growth. Of course we know of some areas that could be investigated and many numerical data recorded, but we are uneasy in not knowing how to make use of the data. As physicists we especially like to make progress synthesizing specialized concepts into more general forms. We savor the similarities -- and differences -- when ideas developed in one area prove useful in another set of circumstances. Just now it is optical resonance physics that seems to be ripe for explosive growth using new laser techniques and “classical” resonance ideas. This paper represents a direct effort to sketch, in the opinion of a certain class of partisans, “where the action is.” We begin with a brief discussion of experiments in which a laser is useful but not necessary, and a consideration of the basic optical facts of life. The bulk of the paper explores the exciting land beyond the Doppler limit.
