摘要:

Experimental study of soft x‐ray laser carried out on the LF12 Laser Facility of SIOM (Shanghai Institute of Optics and Fine Mechanics) is reported. Soft x‐ray amplifications were observed in lithium‐like silicon ions by line‐focused laser irradiation of slab targets. Based on the time‐integrated measurements, the gain coefficients are 1.5 and 1.4 cm−1for the 5f–3d(88.9 A˚) and the 5d–3p(87.3 A˚) transitions of lithium‐like silicon ions, respectively. In addition, the spatial characteristics of the laser lines are also presented.
