摘要
有大约 10keV 的很高的动能和为激光紧张的质子精力的浸透效果的质子在和大尺寸的氢簇的超短波的强烈激光脉搏的相互作用被观察了。包括象焦点点上的激光紧张分发一样的簇尺寸分发,理论计算基于一个简化库仑爆炸模型与我们的试验性的大小相比,它在对对方的好同意。
Protons with very high kinetic energy of about lOkeV and the saturation effect of proton energy for laser intensity have been observed in the interaction of an ultrashort intense laser pulse with large-sized hydrogen dusters. Including the cluster-size distribution as well as the laser-intensity distribution on the focus spot, the theoretical calculations based on a simplified Coulomb explosion model have been compared with our experimental measurements, which are in good agreement with each other.
