摘　　要：采用新颖的“双靶对接”设计,利用强度约12×10^(13)W/cm^2,波长1.05μm,脉宽约1ns的两路激光线聚焦辐照平面厚锗双靶,观察到了波长为19.6、23.2、23.6、24.7和28.6nm的五根类Ne锗3p-3s跃迁谱线的放大。波长为23.2和23.6nm的谱线,增益-长度乘积GL的值约13。利用软X光扫描相机观测了四根软X光谱线的时间特性。By means of a novel experimental design named 'Double-Target Coupling', amplifications of five lines at wavelengths of 19.6, 23.2, 23.6, 24.7 and 28.6nm from the 3p - 3s transitions in neon-like germanium plasmas have been observed. The germanium slabs were irradiated by two opposing laser beams with the irradiance of 1.2×1013W/cm2 at line foci in the -lns pulses. The values of GL, the product of gain and plasma length, of the lines at 23.2 and-23.6nm, were both about 13.Using a soft x-ray streak camera, temporal be haviours of four lines were recorded and studied.
