| 摘 要： | Experimental studies of soft X-ray laser for the sodium-likerecombination scheme conducted at the LF12 Laser Facility of SIOM(Shanghai Instituteof Optics and Fine Mechanics)are reported.Soft X-ray amplification was observed insodium-like copper ions by line-focused laser irradiation of slab targets.Based on thespatially-resolved measurements,the spatial distribution of the laser gain for the transition6g—4f(72.22(?))of sodium-like copper ions was obtained,and the maximums of gaincoefflcients and gain-length products at 550μm from target surface were 2.0 cm~(-1) and 3. 6,respectively.The evolution of spectrally discriminated spatial uniformity of line-shapedplasmas as lasing gain media produced by uniform laser illumination in line-focus isalso investigated.It is found that under this experimental condition the line-shapedplasma is very uniform after laser heating.

| Abstract: | Experimental studies of soft X-ray laser for the sodium-lika recombination scheme conducted at the LF12 Laser Facility of SIOM (Shanghai Institute of Optics and Fine Mechanics) are reported. Soft X-ray amplification was observed in sodium-like copper ions by line-focused laser irradiation of slab targets. Based on the spatially-resolved measurements, the spatial distribution of the laser gain for the transition 6g-Af (72.22 A)of sodium-like copper ions was obtained, and the maximumfl of gain coefficients and gain-length products at 550/,m from target surf ace were 2. Ocm"1 and 3.6, respectively. The evolution of spectrally discriminated spatial uniformity of line-shaped plasmas as lasing gain media produced by uniform laser illumination in line-focus is also investigated. It is found that under this experimental condition the line-shaped plasma is very uniform after laser heating. |
