An external cavity laser assembly (10) that generates a light beam (12) includes a gain medium (14) and a diffraction grating (24). The gain medium (14) has a growth direction (14C), a fast axis (14A), a first facet (34A), and a second facet (34B) that is spaced apart from the first facet (34A). The gain medium (14) emits from both facets (34A) (34B). Further, a beam polarization (30) of the light beam (32) emitting from the second facet (34B) is perpendicular to the growth direction (14C) and the fast axis (14A). The grating (24) includes a plurality of grating ridges (24A) that are oriented parallel to the beam polarization (30). Moreover, each of the grating ridges (24A) can have a substantially rectangular shaped cross-sectional profile.
