| Popis: | 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. |
