0.53μm激光与等离子体相互作用实验研究
-
摘要: 利用神光–I激光装置的南路光束经KDP晶体倍频后的0.53μm激光与金盘靶相互作用,重点研究了吸收、X光转换、SRS超热电子和离子发射行为。结果表明,采用短波长激光,吸收和X–光转换率明显提高,SRS及超热电子的产生得到了明显抑制。Abstract: Experimental investigation of 0.53m m laser –plasma interaction were conducted on Shenguang–I laser facility, with one of its two beams irradiating on gold disks. The absorption、X –ray conversion、stimulated Raman scattering、hot electrons generation and ions emission were investigated. Experimental results show that absorption and X ray conversion are enhanced, SRS and hot electrons generating were suppressed by shortening laser wavelength in comparision with 1.053μm laser.
