free space propagation

基本解釋

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(jīng)過軸棱錐轉(zhuǎn)換后產(chǎn)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.
使用復(fù)解析信號(hào)法研究了束寬與頻率無關(guān)的超短脈沖貝塞爾-高斯光束在自由空間的傳輸特性。
