Stability of widely tuneable, continuous wave external-cavity quantum cascade laser for absorption spectroscopy
The performance of widely tuneable, continuous wave (cw) external-cavity quantum cascade laser (EC-QCL) has been evaluated for direct absorption spectroscopy measurements of nitric oxide (NO) in the wavenumber range 1872-1958 cm-1 and with a 13.5 cm long optical cell. In order to reduce the absorpti...
