Multi-mode absorption spectroscopy using a quantum cascade laser for simultaneous detection of NO and H2O
{{output}}
Detection of multiple transitions in NO and H2O using multi-mode absorption spectroscopy, MUMAS, with a quantum cascade laser, QCL, operating at 5.3 μm at scan rates up to 10 kHz is reported. The linewidth of longitudinal modes of the QCL is derived from pres... ...
