普林斯顿大学的研究人员在降低量子级联激光器(QCL)的阈值电流和提高其性能的实验中,偶然发现了一种QCL全新光发射机理,即QCL能克服传统损失发射双光
Researchers at Princeton University, in an effort to lower the threshold current and improve the performance of quantum cascade lasers (QCLs), came across a QCL new light-emitting mechanism that overcomes the traditional loss of dual-light
