Abstract:

Efficient, high power diode lasers with an extremely low vertical divergence angle (termed here ELOD designs) are produced when super large optical waveguide designs are combined with low index quantum barriers. Small divergence angles are required for lowloss beam shaping and lead to lower costs of optical systems. They are especially important when spectral stabilization with an external volume Bragg grating is necessary. A review of recent progress in performance of high power broad area ELOD single emitters at 970 nm and 1065 nm is presented.
