beam spot diameter

基本解釋

Good beam quality, close to the basement membrane, small spot diameter, perfect for ultra-fine marking.
光束質量好，接近基膜，光斑直徑小，完美適用于超精細標記。
Lightwave propagation and mode field evolution are simulated by finite-difference beam propagation method so that the spot diameter is ascertained.
采用光束傳播法數(shù)值模擬了錐形透鏡光纖中的光波傳輸和模斑的演化，確定了錐形透鏡光纖端面出射光斑的大??；
In order to obtain the laser beam with better beam quality, less spot diameter and higher power density in laser manufacturing (LM), Gaussian beam used in LM was transmitted and transformed.
為了獲得光束質量較好、光斑尺寸較小、功率密度較高的、適合激光加工的激光束，對激光加工中的高斯光束進行傳輸與變換。
