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