Paper Abstract

A continuously operating route meter of low concentrations of gases, based on optoelectronic recirculation, is proposed. A semiconductor laser diode with an asymmetric quantum-well heterostructure providing emission at two different wavelengths is used for the radiation source. The regime of opto-electronic recirculation simultaneously at two wavelengths is realized in the system, that makes it possible to perform route measurements of the gas concentration and determine the length of the controlled route with a high accuracy.
