Abstract

An intercavity laser absorption spectrometer was constructed on the basis of the full solid state continues wave YAG:$Cr_{4}^{+}$ laser. In addition of first work $^{a}$ the investigation of linearity and sensitivity of such spectrometer was performed. Dimensions of z-scheme laser setup were optimized to obtain the maximal absorption sensitivity. It was shown that the spectrometer can operate with an equivalent optical path more than 300 km. The sensitivity equal to $10^{9}$ $cm^{-1}$ was reached.
