free space propagation

基本解释

In this paper we study the propagation of the single cycle or much shorter pulsed-beam in free space.
研究了单周期或更短的超短脉冲光束在真空中的传输。
In this thesis, the properties of the free-space propagation and focus were studied when a beam propagates through an axicon.
本论文主要是探讨激光光束经过轴棱锥转换后产生的无衍射光束的传输特性和聚焦特性。
Using a complex analytical signal representation, the free-space propagation properties of ultrashort pulsed Bessel-Gauss beams whose waist width is independent of frequency are studied.
使用复解析信号法研究了束宽与频率无关的超短脉冲贝塞尔-高斯光束在自由空间的传输特性。
