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 new 256 OEM Interrogation monitor showcases a product where we have used our 1550 nm PING gratings to build a highly compact, efficient, robust and cost efficient optical sub-module for integration into your Fiber Bragg grating sensing system.

Finally, recognizing that budgets are tight, we launch an end-of-year campaign offering all universities and R&D labs 20% discount on two of our most popular ROCK spectrometers in the VIS and NIR spectral ranges.

I hope you will enjoy reading the newsletter.

Kind regards, Thomas Rasmussen, VP Sales & Marketing

…take a closer look at our telecom PING gratings or eXtreme Efficiency spectrometer gratings and learn that the Ibsen gratings offer you the markets best broadband performance in terms of high diffraction efficiency, low polarization dependent loss, and environmental stability.

If you are looking for more than just the grating, Ibsen Photonics can also offer robust OEM-modules for both fiber sensing, Raman spectroscopy, and OCT.

[h2]How much power can they take?[/h2]

Newest results on power handling capabilities of Ibsen Phase masks and pulse compression gratings

Ibsen High Power Grating

Ibsen High Power Grating

Ibsen phase masks and pulse compression gratings love being blasted by short, high energy laser pulses and high power CW beams. But just how much power can they take?

Recently provided test results from ICFO have identified a long sought after damage threshold level of our gratings. With 40 femtosecond, 785 nm pulses, damage started occurring at 24.4 TW/cm2. It was furthermore identified that the damage occurred in the fused silica material itself, and not the grating structured surface, which thereby demonstrates the high integrity of the surface-relief grating.

A full test report can be found at High Power, which also includes other results at other wavelengths, pulse lengths etc. We update this page as new results come in – please let us know if you have blasted our gratings with higher energy/power levels than those shown – we are more than happy to include and reference your results.
