长波红外的后向喇曼放大

Backward Raman Amplification in the Long-wavelength Infrared

L. A. Johnson, D. F. Gordon, J. P. Palastro, B. Hafizi

摘要:

等离子体中后向拉曼放大的大量工作集中在极端强度极限上,然而后向拉曼放大也可以提供用于产生强、宽带宽、长波长红外辐射(LWIR)的有效且实用的机制。结合相对论冷流体等离子体模型的电磁模拟被用来演示通过后向拉曼放大产生具有太瓦功率的10微米波长的皮秒脉冲。碰撞阻尼,朗道阻尼,泵浦损耗,和波破碎的影响进行检查,以及由此产生的长波红外拉曼放大器的设计考虑。

英文摘要:

The wealth of work in backward Raman amplification in plasma has focused on the extreme intensity limit, however backward Raman amplification may also provide an effective and practical mechanism for generating intense, broad bandwidth, long-wavelength infrared radiation (LWIR). An electromagnetic simulation coupled with a relativistic cold fluid plasma model is used to demonstrate the generation of picosecond pulses at a wavelength of 10 microns with terawatt powers through backward Raman amplification. The effects of collisional damping, Landau damping, pump depletion, and wave breaking are examined, as well as the resulting design considerations for a LWIR Raman amplifier.
