WebYour skin has three main layers, and the dermis (corium) is the middle layer of skin in your body. The other two layers of skin are your epidermis and hypodermis. Your dermis layer … WebA quantum cascade laser is a heterogeneous diode laser and as with any diode laser, radiation is generated by applying voltage to it. In contrast to a classical homogeneous diode laser that produces only a single wavelength, a QCL can emit light in a range of wavelengths in the mid and far infrared. To do this, the QCL is placed in a so-called ...
