The spatial profiles in the horizontal and vertical direction of lasing line intensity of neon-like germanium were measured. For a 20mm long plasma of 102μm lateral dimension, the main beam in the horizontal direction is found to exhibit an angular divergence of 12 mrad with a offset displaced 8 mrad from the plasma axis and the beam angular divergence in vertical direction is about 22 mrad. In addition, the characteristic of beam optics of the double-pass amplification was diagnosted using a Mo/Si multilayer mirror.
