传播强激光脉冲的等离子体管当光束通过气体传播时，有自然发散的趋势。这种扩束效应使光束通过气体介质前进时恒使光强度变弱。在较长距离上保持光束强度的一种方法是把光束聚焦到光纤内，光纤能约束光，并使光沿玻璃纤芯传播时不加宽。然而，这种方法对强激光脉冲不太奏... Plasma tubes that propagate intense laser pulses tend to diverge spontaneously as the beam travels through the gas. This beam expansion effect makes the light beam constant through the gaseous medium to make the light intensity weakened. One way to maintain beam intensity over longer distances is to focus the beam into an optical fiber that can confine the light and does not widen it along the glass core. However, this method does not play a strong laser pulse ...
