Title :
Mid-IR semiconductor lasers for chemical sensing
Abstract :
Investigations of 3.2-3.6 μm continuous wave InAsSb lasers are reported with respect to spectroscopic applications, their application to methane and formaldehyde measurements as an example. The devices were InAsSb-InAsSbP double heterostructure stripe lasers. The basic, spectral and tuning characteristics at cryogenic temperatures were analyzed using a calibrated automated laser test setup
