Caractérisation de lasers à cascade quantique émettant aux alentours de 10 µm en vue de la réalisation d'un senseur hétérodyne

Abstract : Heterodyne spectroscopy is a passive method which enables to detect and quantize gases. This training period work consists in characterizing the core of a heterodyne sensor : the local oscillator. It is a quantum cascade laser which emits at around 10 μm. This wavelength orresponds to fundamental absorption bands of molecules (the most absorbent bands) which enables to take an interest in low concentration of gases.
