Paper Abstract

Many gas-phase sensing applications involve detection of multiple molecules with rotationallyresolved spectra. The benefits of using mid-infrared (3 - 20 μm) radiation for detection are clear: strong, characteristic absorption features across regions with varying degrees of overlap can be exploited for multi-component detection. Quantum cascade lasers now provide CW radiation throughout the mid-infrared, but there are no commercial lasers available that meet the combined requirements of small size, low power consumption, and continuous broad tuning. Recent progress in realizing these modules is discussed, along with commercial applications enabled by the technology.
