The In Ga As / Al GaAs strained double quantum well laser with two pairs of gradient refractive index (G R I N) heterojunction structures has been successfully fabricated by metal organic compound vapor deposition (MOCVD). The laser has a wavelength of 970 nm to 982 nm, a continuous threshold current density of 140 A / cm 2 at room temperature and a continuous single-sided output power of 520 mW at 0.9 A. When operating at 2.0 A, The output optical power is 1.49 W and the maximum power is 2.4 W. Differential quantum efficiency up to 0.83 W / A.
