摘　　要：利用JB19等程序分别对基频和倍频激光驱动条件下类氖锗X射线激光进行了模拟计算,结果表明利用倍频激光驱动同样也能够获得高强度的类氖锗X射线激光输出,只是对驱动激光的输出要求要高3.3倍.尽管如此,这也为将来在大型激光装置上开展类氖系列X射线激光研究指明了方向.初步的实验研究也证实了利用倍频纳秒激光驱动能够获得类氖锗X射线激光输出的结果.Generally, it is more suitable for studies on Ne-like X-ray laser by using fundamental frequency laser as driving beam than by frequency doubling. However, many huge laser facilities built for ICF research are usually designed for doubling and trebling of laser frequency, and they are unfit for use as fundamental frequency laser. We simulated the Ne-like Ge X-ray laser making use of JB19 codes, respectively in the case of doubled and trebled frequency diving. The results indicated that the higher power output of Ne-like Ge X-ray laser is also obtained when driven by doubled frequency laser. However the required output of driving laser beam was 3.3 times that in the ease of the fundamental. Any way it presents a direction of studying Ne-like X-ray laser with huge laser facilities in the future. A preliminary experimental study has proved this point.
