Abstract: An external cavity with a waveguide – grating mirror (WGM) is proposed for a wide-aperture semiconductor laser. The emission spectra of a laser diode in the cavity were studied for a collinear and noncollinear incidence of radiation on the WGM. The substantial (down to 0.1 nm) narrowing of the emission spectrum was obtained, and a continuos tuning of laser radiation in the range from 10 to 18 nm was demonstrated.
