摘要：

A general solution of the electrostatic potential that determines the maximum light-ion energy is derived for the test-particle acceleration model by taking into account the influence of the substrate-ion density gradient.It is shown that the substrate-ion density structure is also dependent on laser pulse duration.In the picosecond or sub-picosecond regime,the decreasing density gradient of the substrate-ions leads to an evident reduction in the acceleration efficiency of the light-ions.However,this kind of influence is negligible in the ultrashort regime.
