Abstract

Abstract : A low power‐consumption distributed feedback quantum cascade laser (DFB‐QCL) is developed for gas‐sensing in 7 μm wavelength region. The threshold power‐consumption was as low as 0.93 W with the sufficient output power of 20 mW at 20°C under continuous‐wave condition. In addition, it maintained a single‐mode operation between −40 and 50°C without a mode‐hopping, leading to a total wavelength shift of 66 nm. This DFB‐QCL would be suitable for gas‐sensing application.
