利用皮秒脉冲激光驱动瞬态X射线激光

报道了利用皮秒激光驱动产生瞬态类镍银X射线激光的实验结果．采用一路脉冲宽度为数百皮秒的激光作为预脉冲，配合另一路皮秒激光作为主脉冲联合驱动平面靶，获得了一定强度的类镍银X射线激光输出，输出能量约为5-10nJ．

This paper presented the results of experimental studies on transient soft X-ray laser using a picosecond pulsed laser facility. A rather intensive Ni-like Ag X-ray laser at 13.9 nor with output energy of about 5-10 nJ was obtained by irradiating the solid flat targets with a several hundred picosecond long laser pulse in combination with an 1 ps ultra-short laser pulse.
