本文报道用脉宽30 fs ~ 3 ps的激光产生高Z等离子体，靶上功率达10（15-17）W/cm（2），研究了M波段宽X射线辐射。实验发射光谱测量的能量范围从1.50至1.75千电子伏，并讨论作为潜在的背光X射线源的时间分辨X射线吸收光谱研究。它们进行了比较与理论非局部热力学平衡计算的x射线发射。
The investigation of the broad M-band x-ray emission from high-Z plasmas created by a laser, with a 30 fs to 3 ps pulse duration and achieving 10(15-17) W/cm(2) on target, is reported. Experimental emission spectra are measured in the energy range from 1.50 to 1.75 keV and discussed as potential backlighting x-ray sources for time-resolved x-ray absorption spectroscopy studies. They are compared with theoretical nonlocal thermodynamic equilibrium calculations of x-ray emission.
