Abstract
Broad-area semiconductor lasers naturally emits on several lateral modes even at injection currents very close to the threshold current. An external cavity terminated by an apodizing holographic grating has been used to favor the oscillation of only one longitudinal mode and one lateral mode. It is possible to obtain laser oscillation on two different wavelengths simultaneously by using a grating that contains two grating periods. The fabrication technique of the apodizing holographic grating is explained. The spectrally-resolved near-field intensity distributions are presented.
