Abstract
An external cavity semiconductor laser that incorporates a large�area amplifier has been successfully stabilized into a single transverse mode over the 600 μm width of the amplifier. Single�transverse�mode operation is achieved by using the combination of a diffractive mode�selecting mirror and an aperture. 2.8 W of stable diffraction�limited output power is achieved.
