Аннотация
Continuous-wave lasing in the 2.2 μm region is reported for single-mode GaAlAsSb/GaSb/GaInAsSb double-heterostructure diode lasers with thermoelectric cooling. The temperature dependences of the threshold current near room temperature are investigated for the cw and pulsed pumping regimes. A record characteristic temperature T0=132 K has been achieved.
