High continuous wave (cw) optical output power of 10 mW has been achieved from an InAsSb diode laser at 82 K in the 3.6 mu m spectral region. The threshold current has been as low as 37 mA at 82 K with a characteristic temperature of 23 K. It could be shown that in multimode operation of the InAsSb-laser the cw optical output power for a single lasing mode is limited to about 2 mW.
