摘要:
等离子体波导是延长强激光与等离子体相互作用长度的有力工具.文章论述了等离子体波导的基本原理,推导了匹配的光斑半径公式,评述了强激光脉冲等离子体波导的最新研究进展,针对现有毛细管放电等离子体波导和固体激光等离子体波导结构的不足,提出了一种利用高能脉冲CO2激光击穿低压气体产生波导的新方案,该等离子体波导口径小、存续时间长,降低了超强激光束与等离子体波导之间的同步要求.
Abstract:
Propagation of laser pulses in a plasma waveguide has been proposed as an effective means of extending the interaction length with an under dense plasma. Fundamental principles of plasma waveguide is discussed,and then the matched spot size is calculated from Maxwells equations. Recent progress on the laser pulses plasma waveguide and their applications is presented. A new scheme of plasma waveguide using high energy CO2 laser pulse induced lowpressure gas breakdown, which overcomes the shortcomings of capillary gas discharge plasma waveguide and solid laser induced plasma waveguide, is suggested.The plasma waveguide should thus provide guiding for smaller spot sizes over longer interaction time.A time synchronization requirement between high intensity laser beams and plasma waveguide should also be reduced.
