uniform aperture distribution

基本解釋

In this paper, a new method, which uses only one phase aperture to obtain uniform distribution from Gaussian beam, is proposed, the calculation results are given.
本文提出只用一個(gè)簡單的相位光闌實(shí)現(xiàn)高斯光束強(qiáng)度均勻化的新方法，給出了計(jì)算結(jié)果。
The diffraction modulation of ultrashort pulsed-laser is less than that of CW laser, so only serrated aperture can be used to get uniform near-field uniform intensity distribution.
和單色激光的衍射不同，寬帶的飛秒光束衍射調(diào)制較小，直接利用鋸齒光闌，便能獲得近場光強(qiáng)分布相對均勻的光束。
