Abstract
An injection laser includes two substantially parallel mirror side faces and a substantially stripe-shaped contact member having a comparatively large width. The stripe-shaped contact member has a shape and disposition with respect to the mirrors such that laser action can be obtained only in a comparatively narrow stripe of the active layer. For example, the contact member may be arranged to extend obliquely with respect to the mirrors instead of at right angles thereto.
