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

Top Hat Beam shaper
Diffractive beam shapers convert a laser beam with Gaussian intensity distribution into a beam with an accurate andalmost arbitrary intensity distribution. Specific applications include precise control of treatment depth in laser heattreatment, laser hardening, cladding; turning a laser beam into a square or hexagon to increase the fill-factor in laserdirect writing; and laser tweezers, etc.

Intra-Cavity beam shaper
Traditional laser resonators generate laser beams with a Gaussian distribution. By using an intra-cavity DOE, theresonator can extract more energy an d generate a more uniform super-Gaussian beam, thus greatly improve theelectrical-optical conversion efficiency.
Long / short focal depth DOE
DOEs with long or short depth of focus can be achieved without changing the incident beam size or the working distance (focal length) as well as the focal spot size.
Beam sampler
Without affecting the main laser beam, a diffractive beam sampler produces two laser beams which are exactly the same as the main beam except for having lower power. These two low-power laser beam can be used for monitoring the intensity distribution of the main beam. We offer both reflective and transmissive beam samplers.
Beam homogenizer(Diffuser)
One main advantage of a beam homogenizer is its insensitivity to the incident beam quality and the change ofintensity. Hence it is most suitable for the less stable lasers, laser with long pulse duration or multi-pulse laserapplications. Due to the lengthy exposure time, the intensity fluctuation can be averaged to some extent. For acircularly symmetric output beam, the variation in intensity can be further impressed by rotating the beamhomogenizer.
