Terahertz/Mid-infrared Free-electron Laser Based on Linear Accelerator

Nowadays, infrared radiation is widely used in many fields such as chemistry, biology, materials science, agriculture, food industry and medical applications. The infrared radiation can be categorized into 3 frequency regimes: near infrared (NIR), mid infrared (MIR) and far infrared (FIR). The most popular regimes for applications are the MIR radiation with wavelengths of 2 – 30 micron and the FIR radiation including terahertz (THz) radiation with wavelengths of 0.03 - 3 mm. ...
