摘要：

Continuous wave (CW) operation of quantum cascade lasers is reported up to temperatures of 312K. The devices were fabricated as buried heterostructure lasers and episide-down mounted for improved heat dissipation. Fabry-Perot lasers emitted 17 mW of continuous optical power at 292 K and still 3 mW at 311 K at lambda = 9.12 mum. Distributed feedback quantum cascade lasers showed CW single-mode operation up to 260 K at lambda = 9.0 mum with a side mode suppression rate better than 30 dB. (C) 2002 Elsevier Science B.V.
