近日国外网媒报道,奥地利维也纳技术大学的一组研究人员制造出一种新型量子级联激光器,成功输出了1W的太赫兹辐射,打破了此前由美国麻省理工学院所保持的0.25W的世界纪录,成为目前世界上功率最大的太赫兹量子级联激光器。太赫兹射线是波长介于微波与红外之间的一种电磁辐射,由于物质的太赫兹光谱(包括透射谱和反射谱)包含非常丰富的物理和化学信息,太赫兹技术被认为会对通信、遥感、天文、反恐、医学成像以及生 Recently, foreign media media reports, a group of researchers at the Austrian University of Technology in Vienna to create a new type of quantum cascade laser, the successful output of 1W of terahertz radiation, breaking the previously retained by the Massachusetts Institute of Technology 0.25W world Record, become the world’s most powerful terahertz quantum cascade laser. Terahertz radiation is a type of electromagnetic radiation having a wavelength between microwave and infrared. Terahertz technology is considered to be harmful to communications, as the terahertz spectrum (including the transmission spectrum and the reflection spectrum) of the substance contains very rich physical and chemical information, Remote sensing, astronomy, anti-terrorism, medical imaging and biology
