Quartz Story 3: Transforming light into a “shape”…Quartz Top Hat Beam Shaper Opens Up a New World of Precision Machining

Fused Silica μ-Beam Shaper AED-030103-QAB001

Our proprietary quartz micro beam shaper is a compact, highly efficient, multi-wavelength compatible product that is expected to achieve ideal beam control in a variety of industries, including precision processing and medical applications.

Saisei’s μ modules:  μLINEMAN  and  μSQUAREMAN , like DOE-type top-hat beam shapers, use light diffraction to convert a Gaussian beam into a top-hat beam. However, what is noteworthy about them is that they are revolutionary products that solve problems that could not be solved by DOEs.

The surface of a DOE element is fabricated in a stepped shape, resulting in unevenness, which creates multiple unwanted spots (false spots) and reduces light utilization efficiency. Furthermore, DOEs generally only function at their designed wavelengths. Saisei’s microlaser modules, μLINEMAN  and μSQUAREMAN  , solve these issues.

1. Multi-wavelength compatibility (one element can accommodate a wide wavelength range without wavelength dependency)
2. No false spots, no loss of efficiency and improved quality of top hat profiles.
3. Laser power output efficiency is significantly higher at over 60%.
4. Multiple light sources can be installed
5. Improved durability, such as less thermal degradation
6. Conversion to intensity distribution other than top hat (not only parallel lines, but also hunched shoulders and sloping shoulders can be freely used)
7. Streamlining and reducing costs in design and manufacturing processes
8. Customization available
9. Contactless operation allows for beam shaping, avoiding damage to optical elements

Incident wavelength range: 360 to 1300 mm
Light efficiency: up to 100%, no unwanted light (excluding surface reflection)
Illuminance uniformity: cv < 0.15 * cv = coefficient of variation
