标题： Nonlinear absorption of ultrapower laser radiation by relativistic underdense plasma

摘要： 研究了相对论强度激光辐射在稀薄等离子体中的非线性吸收机制，即电子在离子/原子核上的受激韧致辐射吸收机制，并采用低频近似方法。对于相对论麦克斯韦等离子体，在激光场的渐近大值和高电子温度情况下，研究了非线性逆韧致吸收系数。 显示英文摘要

摘要： The nonlinear absorption of laser radiation of relativistic intensities in the underdense plasma by a mechanism of stimulated bremsstrahlung of electrons on the ions/nuclei is investigated in the low frequency approximation. Coefficient of nonlinear inverse-bremsstrahlung absorption is studied for relativistic Maxwellian plasma at asymptotically large values of laser fields and high temperatures of electrons.
