Single transverse mode continuous wave (CW) operation up to 110 mW has been achieved for narrow stripe ridge waveguide laser diodes based on InAsGaAs quantum dots emitting near 1.31 μm. A total output power of 330 mW has been obtained. The maximal modal gain of the ground state transition was measured to be 12 cm-1
