As laser systems advance toward higher power, broader wavelength ranges, and more compact designs, spectral beam combining has emerged as a highly effective method for scaling performance without compromising beam quality.
Ibsen’s fused‑silica transmission gratings are at the heart of this approach. These gratings offer a wide usable bandwidth, enabling the integration of multiple laser wavelengths on a single platform. Their passive nature ensures consistently high efficiency without the need for active stabilization, and their robust fused-silica design can withstand extreme power densities of up to 3 MW/cm².
Here are the key features of our spectral beam combining gratings:
- CW power handling capability >3 MW/cm²
- Low absorption ˂3 ppm
- Low CTE (10⁻⁶)
- Single or dual polarization capabilities
- High efficiency (up to 98%)
- Low wavefront distortion (typical λ/4)
- Customized grating size (up to 100×100 mm)
35 years of perfection: 400,000+ gratings with zero reliability failures
We have perfected the world’s best gratings over 35 years through our expertise and experience. As an ISO 9001 and 13485 certified manufacturer, we combine decades of experience in both prototyping and high-volume production of transmission gratings. Our commitment to superior and consistent quality is proven by over 400,000 gratings deployed in the field, with zero reliability failures or returns.
We ensure supply chain stability through long-standing partnerships with NATO and NATO-allied networks, as well as scalable grating fabrication and assembly in Denmark.
For applications where efficiency matters, whether in telecom devices, high-power lasers, or compact spectrometers, our transmission gratings deliver unmatched performance.
This image captures the record we broke at Ibsen, producing 1,237 gratings on a single wafer.
