Holo/Or’s High Efficiency beam splitters (HEDS) are a special sub-aperture based diffractive optical element (DOE) capable of splitting a beam into Double Spot 1×2 or Quattro Spot 2×2 spots with 97% efficiency and almost no power in undesired orders.

The UVA range causes sun tanning in the human skin. The UVB range causes sun burning. The UVC range is absorbed by DNA and thus can cause cancer and mutations.

HEQS 2×2 splitters increase M2 symmetrically, so no ellipticity will appear, but the spot size will increase for low M2 (single mode) lasers.

Typically, the laser output beam shape is either Gaussian, Super-Gaussian or some other arbitrary shape. These shapes are rarely optimal for industrial laser welding processes. To better tailor the laser output to the process, many welding equipment manufacturers use a Dual-Spot welding process for certain welding scenarios such as:

For these sensitive applications and for costumers interested in high efficiency, Holo/Or has developed a family of novel diffractive beam splitters: High Efficiency Double Spot (HEDS 1×2) and High efficiency Quattro Spot (HEQS 2×2). For scanning  application such as welding and cutting, we offer a specialized sub-type of HEDs- the Scanning HEDs.

In recent years, many industrial applications are making a shift towards automation and utilize high power lasers for that purpose. One application that highly benefits from the use of lasers is industrial welding.

HEDS operate with a sub-aperture approach, and are therefore sensitive to centering and have an effect on the spot shape and size. The spot size in the splitting axis is increased (spot becomes slightly elliptical), and this effect is observed when using single-mode lasers (low M2). For multi-mode lasers the effect is often negligible. We encourage you to contact our Sales for a detailed simulation of the HEDS in your system.

Double Spot 1×2 and Quattro Spot 2×2 beam splitting is a highly useful practice in many applications, including welding, lithography, perforation, cutting and other material processing applications.  Although our standard Double Spot 1×2 beam splitter (DS) and Quattro Spot 2×2 splitters are highly robust and offer up to 81% and 64% efficiency, respectively, for demanding applications the existence of even 1% input power in undesired higher orders is not tolerable.

For low M2(<~4) the beam in focus will have some ellipticity because of added 0.75. For higher M2 values the spots will become symmetrical.

HOLO/OR endeavors to make integration of its diffractive elements into customers’ optical systems as easy as possible and continuously develops simulation tools, video tutorials and application notes.
