Randomly phased geometrical laser array

A novel geometrical laser array is presented in which high far-field intensities can be generated without phase control of the laser elements. The array was analyzed by randomly varying the phasing of the elements and calculating the maximum far-field intensity. In the worst possible phasing conditi...

Description
Summary:A novel geometrical laser array is presented in which high far-field intensities can be generated without phase control of the laser elements. The array was analyzed by randomly varying the phasing of the elements and calculating the maximum far-field intensity. In the worst possible phasing conditions, the maximum far-field intensity remained high and was nearly constant with regard to the number of array elements. By increasing the geometrical spacing factor, the maximum intensity will approach that of a perfectly phased array.
