1064nm Top Hat Diffractive Beam Shaper DOEs
The 1064nm Top Hat Diffractive Beam Shaper DOEs is a diffractive optical element specifically designed for 1064nm wavelength Nd:YAG lasers. Coligh specializes in manufacturing flat-top beam shapers.
1064nm Top Hat Diffractive Beam Shaper DOEs Discription
Our 1064nm top-hat diffractive beam shaper is currently a product specifically customized for the medical aesthetics industry. This flat-top beam shaper is designed specifically for 1064nm wavelength laser systems, converting a Gaussian beam into a uniformly distributed flat-top beam profile. Utilizing in-house research and development manufacturing capabilities, we ensure a steep beam edge, a flat top, and a high diffraction efficiency of over 70%, minimizing energy loss.
1064nm Top Hat Diffractive Beam Shaper DOEs Product Features
- We use fused silica as the substrate, which exhibits excellent resistance to laser damage thresholds and can withstand long-term use of high-energy pulsed lasers. Furthermore, its extremely low coefficient of thermal expansion ensures stable beam shaping under power variations or changes in ambient temperature.
- Currently, circular profiles are available, but square, rectangular, and other profiles can also be developed, as well as custom-designed flat-top spot shapes.
- Besides medical aesthetics, it can also be used in laser cutting, welding, and surface treatment, providing uniform energy to the laser system.
- We can provide customized small-batch trial production as well as flexible supply for large quantities.
- Currently available products can be delivered within 5-7 days, and customized products can be delivered within 4 weeks.
- Versions with and without coatings and with anti-reflective coatings are available.

1064nm Top Hat Diffractive Beam Shaper DOEs Application
- Medical Laser Aesthetics
The flat-top beam shaper is central to high-end medical aesthetics. The 532nm laser can treat vascular lesions such as port-wine stains and spider angiomas. The 532nm flat-top beam shaper DOE can be integrated into medical laser equipment, converting a Gaussian beam into a spot with uniform energy coverage. This ensures target vessels are heated and coagulated evenly, effectively treating vessels of varying diameters. - Laser Material Processing
In manufacturing solar panels or flexible circuit boards, traditional Gaussian beams deliver excessive energy that risks burning through substrates. The 532nm top hat beam shaper ensures uniform energy distribution by generating circular or rectangular DOEs of specified dimensions. This guarantees consistent energy exposure across the entire spot area, enabling uniform and controllable ablation.
