well-focused beam 中文意思是什麼
well-focused beam
解釋
強聚焦注流-
When a collimated - well gaussian laser beam passes through a 27i - phase plate and then focused by a lens, a focused hollow beam ( fhb ) will be generated behind the lens, as a result of the completely ( r = 0 ) and partially ( r 0 ) destructive interference effects around the central region of the beam
當一束準直的高斯光束通過具有2位相分佈的位相片和一個薄透鏡時,這將導致在入射高斯光束中心的完全和部分相消干涉效應,於是在透鏡后就會形成一束聚焦中空光束( fhb ) 。 -
Well focused beam
良聚焦束 -
In optical fiber aspect, the incident beam can be collimated, converted and focused by some kinds of lenses, making the mode of incident beam matched with or near the optical fiber ’ s modes. in this thesis, thorough theoretical analyses and experimental investigations were made for the external optical properties of a 980nm high - power tunnel junction regenerated multi - active - region quantum well stripe - geometry algaas / gaas / ingaas ld and three different stripe - width 980nm high - power
本論文圍繞本實驗室研發的新型隧道再生多有源區980nmalgaas / gaas / ingaas量子阱大功率半導體激光器和多種條寬的單有源區980nmalgaas / gaas / ingaas量子阱大功率半導體激光器的光場外特性、單模階躍折射率光纖和多模漸變折射率光纖的模場特性進行了深入的理論分析和實驗研究。
