Abstract

A compact CO2 and H2O laser spectroscopy sensor based on cost-efficient vertical-cavity surface-emitting lasers for safety and air-quality applications is presented. It implements inherent wavelength calibration to achieve self-monitored and calibration-free operation during sensor lifetime.
