Array mode selection utilizing an external cavity configuration

· Appl. Phys. Lett.; (United States)
We report operation of a ten-stripe, gain-guided, phase-locked diode laser in an external cavity configuration. The laser radiates in a single narrow (1/sup 0/) lobe. Such lasers generally lase in the highest order array mode, L = 10, which radiates in a twin-lobe far-field pattern. With one antireflection-coated facet and a slit spatial filter, the laser has been operated in the L = 1, 2, 3 or 10 array modes. A theoretical explanation of the spatial filter function is included.
