维尔克斯光电代理以色列Holoor高度均匀激光光斑DOE激光匀光元件、激光匀束器，激光匀光元件、激光匀化器、激光匀化片、激光匀化DOE、激光匀化元件、激光匀光器、光束均匀器、激光匀束元件、激光匀化镜、激光扩散片、均匀激光光斑、高度均匀激光光斑

激光匀光元件可以将单模激光或多模激光转化为一个特定形状的均匀光斑，光斑能量的分布具有高度的均匀性，光斑形状可以为圆形、正方形、直线、长方形、六边形、椭圆形等形状。激光匀光元件是获得高质量均匀激光光斑的重要工具。

Holoor公司所生产的激光匀光元件能够在***光斑均匀性的同时，依然能实现锐利的边界和***高的光能利用率。

激光匀光元件的材料一般可以选择熔融石英、塑料、玻璃，适用的波长范围为193nm~10.6um，激光匀化DOE的表面微结构台阶数可设计成2阶、4阶、8阶、16阶，DOE元件的尺寸范围2mm~100mm。DOE可镀增透膜，整体衍射效率达到75%-98%。

Holo/Or激光匀光元件的特点

适用于单模激光和多模激光

DOE的材料为石英、玻璃和塑料，其中石英***为常用

***的光斑均匀性、锐利的光斑边界

准确的光斑发散角，发散角范围从毫弧度到41°（mrad~41deg）

Holo/Or激光匀光元件的应用领域

激光匀化片主要应用在激光加工和医疗美容行业，具体应用如下

金属焊接等

激光材料处理：激光穿孔，烧蚀，划片，打标，切割和焊接

激光测试，检测等

激光医疗，医疗美容

Holo/Or激光匀光元件可以直接使用或结合聚焦镜使用，直接使用的话可以得到在一定范围内得到任意发散角图案。如果配合聚焦镜使用，可以在焦平面内得到所需光斑的大小的衍射图案。

Holo/Or激光匀光元件***后输出的光斑质量和输入激光的参数有很大关系，大体上，我们可以将激光分为两种：

1.M2<5的单模激光器，其相干性很好，在这种情况下，能实现很陡峭的边界，匀化效果较好，不过不是的均匀（有少量波纹）。对于光束质量较好的入射激光，匀化片一般还会出现0级衍射的***点，即在目标光斑的正中心产生一个亮点。

2.M2>5的激光器，这时入射激光通常为发散角较大或者的多模激光，而不是一个近高斯的光束。这种情况下，匀化器得到的光斑均匀性会大大***，得到一个非常理想的平顶，完全消除波纹，同时边界的过渡区会拉长，表现为边界***陡峭/锐利

Holo/Or高均匀性激光匀光元件（Highhomogeneity,HHDiffuser）

0级中心亮点的问题困扰着很多客户，国内的产品一般都不能很好地客服这个问题。

为了解决激光匀光元件的0级中心亮点问题，Holoor推出了一套高均匀性激光匀化片。其采用双衍射面的方案，用个衍射面降低入射激光的相干性，***个衍射对激光进行扩散，这样就能够得到具有更高的均匀性和***的的零阶效应。使M2<5的单模激光也能得到非常好的匀化效果，使激光匀化DOE满足各种入射激光光束的要求。

应用实例-对光纤输出的激光进行匀化

激光器输出的激光耦合到多模光纤中，通过聚焦透镜和激光扩散器在远场或者在焦平面上实现均匀的强度分布。由于光纤便于集成到各种机械机构中，这就为激光匀化片的应用带来***的方便。

输出模式的数量与光纤长度、纤芯直径成正比。光纤的输出模式将会通过衍射匀化，在焦平面上得到一个非常好的平均输出均匀。
