waist width 中文意思是什麼
waist width
解釋
后胸闊-
It is shown that the fgb and sgb passing through a paraxial abcd system demonstrate similar irradiance profile at the positions of the equal generalized fresnel number. but the fgb and sgb passing through a paraxial abcd optical system having spherically aberrated lens do not demonstrate similar irradiance profile at the positions of the equal generalized fresnel number. the nearly same irradiance profile at the positions of the equal generalized fresnel number can be achieved if the fgb and sgb have the same a / 2 - factor and waist width
在此基礎上首次對相同m ~ 2因子、四川大學博士學位論文不同束腰寬度的平頂高斯光束和超高斯光束作了比較,發現具有棋同礦因子、不同束腰寬度的平頂高斯光束和超高斯光束在近軸abcd光學系統中傳輸時,在菲涅爾數相同的兩個面上具有相側的光強分佈 -
By the method of matrix optics, the waist width and imaging distance of gaussian beams through the coupling system are calculated. by the result of the calculation, a set of double planoconvex lens coupling system are designed and manufactured. the coupling efficiency is up to 92 %
利用矩陣光學的方法,計算了高斯光束經耦合系統聚焦后的像距和束腰寬度,以此為指導設計加工了一套雙平凸鏡耦合系統,耦合效率達92 ;在以上基礎上研究了泵浦光與振蕩光在激光晶體中的匹配,計算出了泵浦光經耦合系統后的最佳焦點位置。 -
