研究了峰值强度为1×10≈⁹W/cm~2的25TW激光与Xe团簇的相互作用。在3.4 Mpa的硬X射线CCD上观测到了能量约为30keV的Xe K壳层X射线。此外，我们还研究了在恒定激光能量下，改变激光脉冲宽度对Xe K壳层X射线产额的影响，发现在产生Xe K壳层X射线时，脉冲宽度为40fs比脉冲宽度为300fs要好。
The interaction between a 25 TW laser and Xe clusters at a peak intensity of 1 × 10¹⁹ W/cm² has been investigated. Xe K-shell x rays, whose energies are approximately 30 keV, were clearly observed with a hard x-ray CCD at 3.4 MPa. Moreover, we studied the yield of the Xe K-shell x rays by changing the pulse duration of the laser at a constant laser energy and found that the pulse duration of 40 fs is better than that of 300 fs for generating Xe K-shell x rays.
