摘要
采用“多靶串接”设计,利用强度为0.8×10^(13)～1.0×10^(13)W/cm^2,波长为1.05μm,脉宽约1ns的两路钕玻璃激光线聚焦辐照四块串接的平面厚锗靶,观察到波长为23.2和23.6nm的接近饱和的类Ne锗软X光激光输出。当总靶长为5.6cm时,这两种波长的软X光激光输出的GL值都达到16左右,沿靶法线和靶平面方向的发散角都只有3～4mrad。
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.
