We provide custom DOEs such as but not limited to:

• Beam splitter (Fan-out)

  • Beam splitters can be used for simultaneous laser drilling (perforating) of multi-holes, fiber coupling, etc. Specific applications of laser drilling include pre-weakening of cartons and metal-foils in packaging industry, high-speed laser texturing, cigarette filters, etc. We can split a single beam into up to a million highly uniform beams.

  

• Beam shaper

  • Diffractive beam shapers convert a laser beam with Gaussian intensity distribution into a beam with an accurate and almost arbitrary intensity distribution. Specific applications include precise control of treatment depth in laser heat treatment, laser hardening, cladding; turning a laser beam into a square or hexagon to increase the fill-factor in laser direct writing; and laser tweezers, etc.

  

• Beam homogenizer (Diffuser)

  • One main advantage of a beam homogenizer is its insensitivity to the incident beam quality and the change of intensity. Hence it is most suitable for the less stable lasers, laser with long pulse duration or multi-pulse laser applications. Due to the lengthy exposure time, the intensity fluctuation can be averaged to some extent. For a circularly symmetric output beam, the variation in intensity can be further impressed by rotating the beam homogenizer.
