維爾克斯光電代理以色列Holoor高度均勻激光光斑DOE 激光勻光元件、激光勻束器，激光勻光元件、激光勻化器、激光勻化片、激光勻化DOE、激光勻化元件、激光勻光器、光束均勻器、激光勻束元件、激光勻化鏡、激光擴散片、均勻激光光斑、高度均勻激光光斑

激光勻光元件可以將單模激光或多模激光轉化為一個特定形狀的均勻光斑，光斑能量的分布具有高度的均勻性，光斑形狀可以為圓形、正方形、直線、長方形、六邊形、橢圓形等形狀。激光勻光元件是獲得高質量均勻激光光斑的重要工具。

Holoor公司所生產的激光勻光元件能夠在保證光斑均勻性的同時，依然能實現銳利的邊界和保證高的光能利用率。

激光勻光元件的材料一般可以選擇熔融石英、塑料、玻璃，適用的波長范圍為193nm~10.6um，激光勻化DOE的表面微結構臺階數可設計成2階、4階、8階、16階，DOE元件的尺寸范圍2mm~100mm。DOE可鍍增透膜，整體衍射效率達到75% - 98%。

Holo/Or激光勻光元件的應用領域

激光勻化片主要應用在激光加工和醫療美容行業，具體應用如下

金屬焊接等

激光材料處理：激光穿孔，燒蝕，劃片，打標，切割和焊接

激光測試，檢測等

激光醫療，醫療美容

Holo/Or激光勻光元件可以直接使用或結合聚焦鏡使用，直接使用的話可以得到在一定范圍內得到任意發散角圖案。如果配合聚焦鏡使用，可以在焦平面內得到所需光斑的大小的衍射圖案。

Holo/Or激光勻光元件后輸出的光斑質量和輸入激光的參數有很大關系，大體上，我們可以將激光分為兩種：

1. M2<5的單模激光器，其相干性很好，在這種情況下，能實現很陡峭的邊界，勻化效果較好，不過不是的均勻（有少量波紋）。對于光束質量較好的入射激光，勻化片一般還會出現0級衍射的極大點，即在目標光斑的正中心產生一個亮點。

2. M2>5的激光器，這時入射激光通常為發散角較大或者的多模激光，而不是一個近高斯的光束。這種情況下，勻化器得到的光斑均勻性會大大，得到一個非常理想的平頂，消除波紋，同時邊界的過渡區會拉長，表現為邊界不再陡峭/銳利

Holo/Or高均勻性激光勻光元件（High homogeneity, HH Diffuser）

0級中心亮點的問題困擾著很多客戶，國內的產品一般都不能很好地客服這個問題。

為了解決激光勻光元件的0級中心亮點問題，Holoor推出了一套高均勻性激光勻化片。其采用雙衍射面的方案，用個衍射面降低入射激光的相干性，個衍射對激光進行擴散，這樣就能夠得到具有更高的均勻性和更低的的零階效應。使M2<5的單模激光也能得到非常好的勻化效果，使激光勻化DOE滿足各種入射激光光束的要求。

應用實例-對光纖輸出的激光進行勻化

激光器輸出的激光耦合到多模光纖中，通過聚焦透鏡和激光擴散器在遠場或者在焦平面上實現均勻的強度分布。由于光纖便于集成到各種機械機構中，這就為激光勻化片的應用帶來極大的方便。

輸出模式的數量與光纖長度、纖芯直徑成正比。光纖的輸出模式將會通過衍射勻化，在焦平面上得到一個非常好的平均輸出均勻。

激光勻光元件的選型

設計激光勻光元件這一類型的DOE首先需要知道如下激光參數
