Optimization of the Spectral Composition of Radiation from a Compact CO2 Laser for an Optoacoustic Gas Analyzer for SF6
A simplified mathematical model and the results of experimental studies on the spectral composition of radiation of a compact waveguide CO2 laser with RF excitation for a optoacoustic laser gas analyzer are presented. The aim is to improve measurement accuracy by eliminating unwanted 10R branch lines from the laser spectrum. Laser radiation signatures are measured under various resonator and active medium parameters without the use of additional selection elements. It is demonstrated that optimal signatures can be achieved by selecting appropriate gas mixture pressure, transmittance coefficient of the output mirror, and optimal resonator length, which can be obtained by varying the nominal (base) length within a range of 2 mm. The effectiveness of optimizing the spectral composition of laser radiation is practically confirmed by statistical results for 64 lasers. This opens up new possibilities for improving the measurement accuracy of the laser optoacoustic SF6 gas analyzer and extending its application in various fields of science and technology.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
