A thick electroplated gold layer was deposited on top of the laser to improve heat dissipation. Devices with one facet high reflection coated produce a maximum output power of 175 mW at 40% duty cycle at room temperature and continuous-wave operation up to 278 K. %@ 0013-5194 %T High-power spatial singlemode quantum cascade lasers at 8.9 µm %B Electronics Letters %D March 2005 %V 41 %N 7 %P 418-419 %I Institution of Engineering and Technology %U https://digital-library.theiet.org/;jsessionid=err70925d35r9.x-iet-live-01content/journals/10.1049/el_20058046 %G EN
