摘要：

Effects of electron temperature on dielectric function and localization of laser beams in underdense collisional plasmas are investigated.Simulation results show that the electron temperature has a strong effect on the dielectric constant and the laser beam localization.It is observed that due to the influence of the electron temperature,the dielectric function presents some interesting and complicated nonlinear variations,and gives rise to the laser beam localization.Moreover,the amplitudes of the beam width and the beam intensity are subjected to continuously oscillatory variation in the region of localization.In addition,the effects of several parameters on the dielectric function and the beam localization are discussed.
