Abstract
Laser spectroscopy based trace gas detection systems are implemented in various applications: industry, medicine, homeland security, environmental monitoring and several more [1]. More sophisticated applications require simultaneous monitoring of several gas species, that possess strong absorption lines in the mid-IR wavelength region. This usually requires using several independent laser sources that will enable targeting the desired transitions of the analytes – for example relatively expensive quantum cascade lasers [2].
