A phase-unifying unstable cavity of magnification factor M=5.8 has been applied to a high-power, commercial XeF laser, and the measurements for characterizing near- and far-field beam properties are reported. A laser beam of 280 mJ, 30 ns duration, a cross section of 2.4×1.3 cm2, and a beam quality factor of 4.3 along the discharge direction (x axis) and of 2.1 along the y direction has been obtained. The beam exhibits a smooth far-field profile with more than 90% of the total near-field energy within a far-field full angle θ⩽0.04 mrad. The beam angular stability is of 0.009 and of 0.004 mrad along x and y, respectively.
