The Measurement of Fundamental Constants (Metrology) and Its Effect on Scientific and Technical Progress
It is perhaps appropriate that in this year 1975, which marks the centenary of the Systeme Metrique and that of the Bureau International des Poids et Mesures, scientific activity in the field of Metrology appears to be flourishing. This is witnessed on the one hand by the number, range and quality of the contributions to this Symposium and, on the other, by the importance which most of the 44 Governments affiliated to the BIPM attach both to their Basic Laboratories and to the network of technical centers engaged in developing measuring methods and in disseminating their results to all levels of the various branches of industry. Should this state of affairs be considered a happy but ephemeral stage in the march of science, or does it represent a tendency of fundamental importance in the evolution of science and technology ? Enough is now known about the history of civilization for us to affirm that, even since the Renaissance, Metrology has payed an ever greater part in both scientific and civic activities.
Theory of Saturated-Absorption Line Shapes
A general theory of the saturated-absorption phenomenon in a two-level atomic system is developed, in which the phase relationships between the oscillating atomic dipoles as well as the population differences between energy levels are taken into account. The absorbing gaseous medium considered in this theory is subjected to irradiation by a quasi-running-wave composed of a strong pump field and a weak probe field propagating in opposite directions. Some new interesting results, not predicted by the so-called hole-burning or rate-equation model, are obtained. In particular, the probe-field-transmission peak line shape is found to be markedly different from what is expected according to the rate equations. For finite Doppler widths and a strong saturating pump field, absorption of the probe field can even change sign, and amplification of this field can actually occur. All these features are explained by a close inspection of the evolution of each atomic ensemble of given velocity. Detailed comparison with similar phenomena already observed in rf experiments is presented and permits us to clarify the new predicted effects.
