Novel mono mode interband cascade laser sources for challenging TLAS applications in the MIR

Tunable Laser Absorption Spectroscopy (TLAS) in the mid-infrared (MIR) wavelength region from 3 to 6 µm has proven to be a versatile tool for a variety of challenging gas sensing applications, especially for many technologically or environmentally relevant gases like e.g., methane or sulfur dioxide.
