本文用解析和数值方法研究了非理想等离子体密度和非高斯横向光强分布对激光韦克菲尔德加速器的影响。我们发现，纵向密度起伏的特征幅度和尺度长度对电子聚束的最终能量有影响。找到了使等离子体纵向密度涨落作用最小的条件，并研究了高阶拉盖尔-高斯激光脉冲的影响。我们发现，高阶激光模式通常会导致较低的能量增益。然而，高阶模式的某些组合可能导致更高的电子能量增益。
We examine the influence of non-ideal plasma-density and non-Gaussian transverse laser-intensity profiles in the laser wakefield accelerator analytically and numerically. We find that the characteristic amplitude and scale length of longitudinal density fluctuations impact on the final energies achieved by electron bunches. Conditions that minimize the role of the longitudinal plasma-density fluctuations are found. The influence of higher order Laguerre–Gaussian laser pulses is also investigated. We find that higher order laser modes typically lead to lower energy gains. Certain combinations of higher order modes may, however, lead to higher electron energy gains.
