Improved sensitivity of tunable-diode-laser open-path trace gas monitoring systems

Not Accessible

Your library or personal account may give you access

Abstract

The detection sensitivity of a long-path atmospheric pollutant monitor using tunable diode lasers has been greatly improved to about 0.1%. These improvements directly result from measurements made on the low frequency noise characteristics of several diode lasers and the temporal spectrum of atmospheric turbulence. Optimum modulation frequencies are given, and an improved optical design is recommended.
