        abstract = {A sensitive gas detection system using a distributed feedback CW Quantum Cascade Laser (QCL) centered at 4610 nm as a radiation source has been developed. QCL was used in combination with an off-axis integrated cavity output spectroscopy for Carbon Monoxide (CO) gas detection in a low gas pressure. a 15 cm long high-finesse cavity with an effective optical path length of 400 m has been used as a sample gas cell. We demonstrated detection limits of an up to 1 ppb level with less than 2 second averaging time. The result clearly showed that The QCL based ICOS system is a robust technique that suitable for fast and sensitive gas detection.}
