Abstract

A Lorentz beam array presents a good model to study a coherent diode laser array, which is an efficient radiation source for high-power beaming use. We present a detailed study of the propagation properties of a Lorentz beam array. Closed-form intensity distribution in the spatial frequency domain is deduced, and the effect of phase errors on the far-field intensity pattern is studied in detail. M 2 factors for two limiting cases, i.e., coherent and incoherent combined laser arrays, are derived and compared. The pro pagation property of the Lorentz beam array is also compared with Gaussian and flat-topped beam arrays.
