本文利用热量子等离子体中的量子介电响应来模拟高斯光束在等离子体中的相对论自聚焦。我们对相对论热量子等离子体中束宽参数与传输距离的关系进行了广泛的参数研究。我们研究了费米温度在自聚焦现象中的作用。结果表明，与相对论冷量子等离子体和经典相对论等离子体相比，热量子等离子体中的量子效应引起了更大的束宽参数振荡和更好的相对论聚焦。与前人的工作相比，我们的计算结果更加可靠。
In the present paper, we have employed the quantum dielectric response in thermal quantum plasma to model relativistic self-focusing of Gaussian laser beam in a plasma. We have presented an extensive parametric investigation of the dependence of beam-width parameter on distance of propagation in relativistic thermal quantum plasma. We have studied the role of Fermi temperature in the phenomenon of self-focusing. It is found that the quantum effects cause much higher oscillations of beam-width parameter and better relativistic focusing of laser beam in thermal quantum plasma in comparison with that in the relativistic cold quantum plasma and classical relativistic plasma. Our computations show more reliable results in comparison to the previous works.
