    Abstract

    This letter describes a novel 980-nm parabolic bow-tie laser array (PBTLA) that is suitable for high-power and high-brightness operation. Output powers in excess of 2.5 W/facet pulsed in a 1° (lateral) beam, less than twice the diffraction limit, corresponding to 275MW•cm-2•sr-1 brightness, have been measured without the use of external lenses from uncoated PBTLAs fabricated in-house (top metal contact surface area ~ 0.1 mm2). Experimental results presented in this letter indicate that coherence effects are significant in the operation of such devices. Theoretical models based on the simple diffraction theory and on the coupled-mode theory have been used to interpret the experimental results.
