Laser-to-proton energy transfer efficiency in laser-plasma interactions

E. Fourkal, I. Velchev, C-M. Ma

摘要:

结果表明,在激光与物质相互作用实验中,通过将入射激光脉冲分成多个等强度的相互作用阶段,可以显著提高加速质子的能量。从热力学的角度来看,分裂过程可以被看作是一种有效的方式,增加从激光到质子的能量转移的效率,其峰值的过程具有最小量的熵增益。据预测,它应该是可能的,以实现$\apprge 100%$增加的能量效率相比,一个单一的激光靶相互作用方案的六级激光质子加速器。

英文摘要:

It is shown that the energy of protons accelerated in laser-matter interaction experiments may be significantly increased through the process of splitting the incoming laser pulse into multiple interaction stages of equal intensity. From a thermodynamic point of view, the splitting procedure can be viewed as an effective way of increasing the efficiency of energy transfer from the laser light to protons, which peaks for processes having the least amount of entropy gain. It is predicted that it should be possible to achieve $\apprge 100%$ increase in the energy efficiency in a six-stage laser proton accelerator compared to a single laser-target interaction scheme.
