摘要
By means of a novel experimental design named the 'double target coupling', the ampli-fications of five lasing lines with wavelengths at 19.6, 23.2, 23.6, 24.7 and 28.6 nm fromthe 3p-3s transitions in Ne-like Ge plasmas were observed. The germanium slab targets wereirradiated by two opposite line-focused laser beams with the irradiance of 1.2×10^(13) W/cm^2.The values of GL (a gain-length product) for the lines at 23.2 and 23.6 nm exceed 13. Themeasurements of temporal resolution for the lasing lines were made with a soft X-ray streakcamera, and the measured results are presented. The divergence and refraction of X-ray laserbeam were also observed.
