| 摘要 | A novel quantum cascade (QC) laser comprises a multiplicity of identical repeat units, with each repeat unit comprising an active region and an injector region. The injector region comprises quantum wells and barriers, selected to facilitate, under appropriate bias, resonant carrier transport from a lower energy level of a given active region to an upper energy level of an adjacent downstream active region. Carrier transition from the energy level to a lower energy level of an active region results in emission of infrared radiation. The laser is advangeously used in, e.g., a measurement system for detection of trace compounds in air. |
| 其他摘要 | 一种新型量子级联（QC）激光器包括多个相同的重复单元，每个重复单元包括有源区和注入区。注入区包括量子阱和势垒，选择这些量子阱和势垒以在适当的偏压下促进从给定有源区的较低能级到相邻下游有源区的较高能级的谐振载流子传输。从能级到有源区的较低能级的载流子跃迁导致红外辐射的发射。激光器有利地用于例如用于检测空气中痕量化合物的测量系统。 |
