Abstract
By use of "series multi-target coupling", the Ne-like Ge soft x-ray lasers output at wavelengths of 23.2 and 23.6nm were observed on a line-focused two-beam Nd-glass laser at 1.05μm. The pulse width was about 1ns, while the irradiance 0.8 × 1013～1.0× 1013W/cm2 on the target surface. For the total target length of 5.6cm, GL values reached 16 or so, and the divergence angles in the directions of both the target normal and target plane were all 3～4mrad.
