Room-temperature continuous-wave operation of a 1.5 µm range GaInNAs laser grown by metal organic chemical vapour deposition is reported. The lasing wavelength of the GaInNAs/GaAs double quantum well laser was 1.50 µm and the threshold current was 245 mA. The characteristic temperature between 10 and 50°C was about 119 K under pulse operation.
