In this letter we report on visible cw single quantum well (AlGa)As diode lasers grown by metalorganic chemical vapor deposition. The operating wavelength is 7210 Å. A linear output power up to 10 mW for a threshold current of 75 mA is achieved. The laser consists of a single quantum well double heterostructure with a 9-μm-wide proton implanted stripe. Double peaked far-field patterns, modulation bandwidths to 2.7 GHz, and a flat noise spectra with a reduced shot noise peak at 2 GHz are obtained.
