Beam shaper for high power laser

We manufacture a beam shaper using a reflective DOE (Diffractive Optical Element) that is compatible with high power lasers exceeding 10 kW.
We design, manufacture, and provide patterns according to the customer's laser specifications (wavelength, beam shape, single mode, multimode, beam size, etc.) and the desired output beam shape.
Upon request, we also provide individual support for mounting jigs. Please feel free to contact us.

reflection type beam shaper

Transmission-type diffraction elements (DOEs), which are generally used for beam shape conversion, cannot maintain their performance due to the effects of heat generation when applied to high-power lasers, even if light absorption is slight. is limited.
NTT-AT 's reflective beam shaper can directly cool the element using a cooling unit, so it can demonstrate its performance even with a high power laser of over 10 kW class.

Beam shaper applications

Lasers are used in a wide range of fields such as cutting, drilling, welding, marking, annealing, and ablation. increase.
