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

Dear reader, In this Ibsen Photonics Newsletter we address a wealth of different applications across all our product lines. For instance, the first section on our high efficiency PING gratings addresses such wide application areas as telecom wavelength selective switching, Raman spectroscopy, optical coherence tomography, and fiber optical sensing. With one of the unique advantages of our fused silica transmission gratings being unmatched energy and power handling capabilities, this newsletter will include an update on the latest field results on this subject, which is especially relevant for users of our Phase masks and pulse compression gratings. The section on our
