摘要:   本文提出利用基片型全像光學元件來設計雷射二極體的準直元件.
此全像準直元件的模型構想,是將雷射二極體的光源準直及光束橫截面形
狀校正之問題於單一元件上作設計.本文由基本全像成像公式及像差理論
的討論,並採用遞迴式全像記錄法,來評估此一元件之最佳記錄參數.在
實驗上我們以自製之重鉻酸銨明膠為記錄材料,配合短波長記錄長波長重
建技術及柱面波干涉方式來製作全像光柵.實驗結果顯示所設計之全像準
直元件在一公尺量測範圍內有良好的準直性,此外對雷射二極體光源入射
偏離角度約有5度的寬容度.
We present a laser diode collimating and beam-shaping optics
using substrate-mode holograms. These elements have many merits,
such as thenormal input andoutput coupling , low aberrations ,
beam collimation and shaping in a compactmonolithic substrate .
This substrate-mode laser diode collimator is based on the
total internal reflection guiding and characteristics of
the re-construction of the cylindrical waves .Using the
hologram image formulas, thehologram aberration theory and the
intermediate hologram recording approach, we can derive the
required design parameters . We have also fabricated
thiselementand test its feasibility using the self-made
dichromate gelatinholographic films . The collimated and
shaped outputs of the test laserdiodeare shown in this article.
