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.
研究了單周期或更短的超短脈沖光束在真空中的傳輸。
In this thesis, the properties of the free-space propagation and focus were studied when a beam propagates through an axicon.
本論文主要是探討激光光束經過軸稜錐轉換後産生的無衍射光束的傳輸特性和聚焦特性。
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.
使用複解析信號法研究了束寬與頻率無關的超短脈沖貝塞爾-高斯光束在自由空間的傳輸特性。
