摘要：

Buried heterostructure quantum cascade lasers emitting at 5.64 mum are presented. Continuous-wave (CW) operation has been achieved at -30degreesC for junction down mounted devices with both facets coated. A 750 mum-long laser exhibited 3 mW of CW power with a threshold current density of 5.4 kA/cm(2).
