Intensities and half-widths of self-broadened N2O have been measured in the 00°1–10°0 band by a spectroscopic method using a stabilized, single line, single mode laser source.On the other hand, line overlap has permitted us to point out a deviation from Lorentz line shape for pressures greater than atmospheric pressure. An attempt to interpret this difference by a semi-empirical formalism is proposed, proceeding from "super Lorentz" line shape recently introduced by Varanasi.

The set up of a stable and monochromatic CO2 laser has necessitated many systematic studies which are described.The observation of beating between modes led us to define the conditions of oscillation of a single mode. The use of a grating in the cavity gave a laser power on a single line. The construction of a single line, single mode laser gave us the possibility of ascertaining the constancy of the length of the cavity and of obtaining a power stability better than 1.5 × 10−2 during 1 h.

We give a general equation which allows the description of the evolution of the laser properties when the gain is varied from below to above threshold. The method is general in the context of the semi-classical theory of lasers. It is numerically illustrated in the simplest case of a single mode laser with a source term characterized by a very narrow spectrum. The transformation of the Airy line shape of the passive Fabry-Perot cavity into the laser line shape is described. A classical linewidth which complements the usual quantum limit can thus be introduced, together with its control parameters.
