报道了波长为λ ~5µm的量子级联激光器在脉冲模式下高达300k的工作。该装置采用了一种新的设计,该设计结合了漏斗注入器和三量子阱有源区域。这是第一个在室温下在该波长范围内工作的中红外半导体激光器。在274k时获得15mw光功率,在300k时获得1.5 mW光功率。
Operation of a quantum cascade laser at λ ~5 µm is reported up to 300 K in pulsed mode. The device uses a new design which incorporates a funnel injector and a three quantum well active region. This is the first mid-IR semiconductor laser operating at room temperature in this wavelength range. Optical powers of 15 mW at 274 K and 1.5 mW at 300 K are obtained.
