摘要：
Performance characteristics of a single frequency mid-infrared quantum cascade distributed feedback (QC-DFB) laser will be reported. Sensitive spectroscopic trace gas detection of CH4, N2O, H2O and C2H5OH in the 7.9 mum spectral region was demonstrated using a 100-m Herriott multipass cell and a rapid "zero-air" back-round subtraction technique.
