A pulsed quantum cascade laser emitting in the wavelength range 9.5 -9.7 mm at 77.4 K is developed based on the GaAs/Al 0.45 Ga 0.55 As heteropair. The laser heterostructure was grown by MOCVD. The threshold current density was 1.8 kA cm -2 . The maximum output power of the laser with dimensions of 30 mm × 3 mm and with cleaved mirrors exceeded 200 mW.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
