论文摘要
根据THZ光和可见光激光器之间的拉曼相互作用，提出了THZ光放大器和相应的方法。两个激光器的频率与Langmuir Wave的频率不同，在背景等离子体中进行了反propa，激发了相当强的Langmuir波。 THZ光放大是通过在提到的Langmuir波的存在下通过THZ光和一种激光器之间的非共振拉曼散射发生的。通常情况下，非共鸣散射不会在E \＆M场之间交换能量，但作者证明了在前置的Langmuir浪潮下可能的可能性。在存在先前存在的Langmuir波的情况下，诱导THZ光与可见光激光器之间的浮动量密度扰动，适合将能量从可见光激光转移到THZ光线。达到条件时，实现有利阶段和放大强度的条件估计为数学公式。增益高达或什至高于100厘米。
A THz light amplifier and the corresponding methods are proposed, based on the Raman interaction between a THz light and visible light lasers. Two lasers, with their frequencies differing by that of a Langmuir wave, counter-propagate inside a background plasma, exciting a rather strong Langmuir wave. The THz light amplification occurs through the non-resonant Raman scattering between the THz light and one of the lasers in the presence of the mentioned Langmuir wave. It is normally the case that the non-resonant scattering does not exchange the energy between E \&M fields but the author demonstrates that it is possible under the pre-exciting Langmuir wave. In the presence of a pre-existing Langmuir wave, the ponderomotive density perturbation between the THz light and the visible-light laser is induced with the phase suitable for transferring the energy from the visible light laser to the THz light. The condition for achieving the favorable phase and the amplification strength, when the condition is met, is estimated as an mathematical formula. The gain is as high as or even higher than 100 per centimeter.
