Abstract

The aim of work was the development of semi-analytical model for evaluation of coherent combining optical systems. The far-field intensity distributions were calculated based on coherent summation of individual Fourier images. To define measures of combining efficiency, Strehl Ratio and Power in Bucket (PIB) distribution were calculated for each case. In such a way we can determine maximal intensity and power content in main diffraction lobe, the horizontal-PIB to define beam diameter at certain level (e.g. 86.5% PIB) and power content for a given beam diameter (vertical-PIB). The effects of the individual tilts and phase errors on the effectiveness of the combining, Strehl Ratio and PIB were investigated.
