    Sammanfattning : The quantum cascade laser (QCL) is a solid state device capable of generating the coherent mid-infrared and terahertz radiation. It is made from layers of different semiconducting materials. This layered structure gives rise to sub-bands, that are employed to achieve charge inversion necessary for lasing. LÄS MER
