Abstract
The performance of computer-automated laser systems to be used in atmospheric gas monitoring is discussed. Factors to be considered are types of lasers to be used, the stability, and the repeatability of these lasers. Special attention is paid to the fundamental mechanism and limitations of CO2 gas and Pb-salt diode lasers. Also considered are the choice of computers, automation, molecular absorption of laser radiation by atmospheric gases, and on-off absorption line switching techniques suitable for field experimentation. A few spectroscopic systems using CO2 and Pb-salt lasers are presented to illustrate useful automated field instrumentation.
