摘要

本文研究了q-高斯激光束与非磁化等离子体的非线性相互作用。在本研究中，相对论非线性和自动机非线性是结合在一起的。利用WKB近似和近轴理论推导了光束束腰随归一化传播距离的二阶ode表达式变化。进一步，通过RK4方法探讨了束腰随归一化传播距离的变化规律。分析了等离子体温度、激光强度、等离子体密度和q参数对束流腰的影响。

Nonlinear Interaction of q-Gaussian Laser Beam with Unmagnetized Plasma: Effect of Relativistic and Ponderomotive Nonlinearity

The present work explores the nonlinear interaction of q-Gaussian laser beam with unmagnetized plasma. Relativistic and ponderomotive nonlinearities are taken together in the present investigation. The Wentzel–Kramers–Brillouin (WKB) approximation and paraxial theory are used for deriving the second-order ODEexpressing variation of beam waist against the normalized propagation distance. Further, the behavior of the beam waist against normalized propagation distance is explored through the RK4 method. The impact of established parameters of laser and plasma such as plasma temperature, laser intensity, plasma density, and q parameter on the beam waist is also analyzed.
