dc.description.abstractMid-infrared semiconductor lasers with broadband emission spectra have been attractive in the past few years due to its broadband characteristics in the mid-infrared wavelength range. Some essential applications including but not limited to spectroscopy, astronomy, imaging, communications, gas/chemical sensing, biomedical sciences, security, and military application sciences. The mid-infrared wavelength range of the spectrum provides many increasingly important applications, such as photon sensors for environmental, industrial or health monitoring, or national defense and homeland security. This has driven the rapid development of MIR semiconductor lasers over the past few decades. This report introduces the general preparation method of QCL, including the fabrication of QCL is introduced. First, its basic features are introduced. The fabrication and process of the experiment are explained. The experimental data results are analyzed and summarized. Furthermore, and the improvements needed of and the experiments and application of QCL in the future is further discussed.en_US
