Abstract: The waveguide design of a laser heterostructure is optimised to expand the laser beam in the vertical direction at the output mirror of a laser diode (up to 1.5 μm at the half intensity for the zero mode). Experimental samples of such diodes operated in the cw transverse single-mode lasing regime up to the output power of 0.5 W. The radiation divergence was 11° — 12° and 4° — 7° in the vertical and horizontal directions, respectively.
