毛细管中的Laser驱动等离子体波
Laser-driven plasma waves in capillary tubes
摘要：
等离子体波的激发超过了长达8厘米的长度，第一次，demonstrated使用激光引导的强激光脉冲通过充满氢气的玻璃毛细管。等离子体波诊断的光谱分析的透射激光辐射。光谱红移的依赖关系，测量作为填充压力，毛细管长度和入射激光能量的函数，是在很好的协议与模拟结果。从模拟中推断出的纵向加速场在1 - 10 GV/m的范围内。
英文摘要：
The excitation of plasma waves over a length of up to 8 centimeters is, for the first time, demon- strated using laser guiding of intense laser pulses through hydrogen filled glass capillary tubes. The plasma waves are diagnosed by spectral analysis of the transmitted laser radiation. The dependence of the spectral redshift, measured as a function of filling pressure, capillary tube length and incident laser energy, is in excellent agreement with simulation results. The longitudinal accelerating field inferred from the simulations is in the range 1 -10 GV/m.
