Laser Optical Engineering supply beam shaping diffractive optical elements, specialising in high power laser applications. We have a unique combined expertise in both diffractive optics and laser materials processing, and can provide a complete laser beam shaping solution. We offer a;
- Standard range of high powered diffractive beam shapers
- Custom produced diffractive optics
- Diffractive Design Service including thermal modelling for process optimisation
- Optical mounting and integration technology for diffractive optics
- Specialist material processing consultancy and support
Our products and expertise enable engineers to accomplish diffractive, high efficiency, laser beam shaping in industrial applications. Our aim is to provide a beam shaping solution that is simple to integrate, easy to align and requires a minimal level of maintenance.
Why Diffractive Optics?
Diffractive optics can shape your high powered laser beam into any pre-specified intensity distribution. They overcome the limitations of conventional optics, and therefore allow beam shapes to be optimised to the process and the material. The use of diffractive optics can improve processing characteristics, process efficiency and allow the realisation of novel applications. Many materials processing applications have been shown to benefit from the use of diffractive optics including;
- Laser transformation hardening (download pdf)
- Laser cladding
- Laser welding
- Laser drilling (download pdf)
- Laser soldering (download pdf)
- Simultaneous cutting/welding (download pdf)
- Laser curing
- Laser branding
- Laser glass cutting
The diffractive optics supplied are all specially designed for high power material processing and as such have the following special features;
- single element beam shaping, no additional focussing lens required leading to reduced system losses.
- high diffraction efficiency >80%
- high power handling capability, up to 3kW
Currently LOE only supplies high powered diffractive elements for the CO2 laser. However, we will shortly be introducing a range of beam shaping optics which operate in the 1μm region.
