Patterns of Change in Voigt Contours of the Weak Absorption Line in a Laser Spectrometer with an Analytical Cavity
Abstract
The variation of the Voigt convolution contour in a spectrometer for measuring of weak absorption consisting of a frequency-tunable laser and an external analytical resonator is studied. It is established how the characteristics of the convolution and the parameters of the resonator affect the reproduction of the shape and width of the absorption line. The effect of absorption saturation on the accuracy of measuring the weak absorption coefficient is discussed.
