Pulse compression gratings

Fused silica transmission gratings

Unbeatable energy/power damage threshold combined with high-efficiency spectral performance

As femtosecond laser systems advance to ever-increasing energy levels, demands on the energy/power handling capabilities of pulse compression gratings increase. Ibsen manufactures 100% fused silica Pulse Compression Gratings that offer unbeatable energy/power handling capacity, combined with high-efficiency, low wavefront distortion performance.

Features and benefits

100% Fused silica gratings provide the highest energy/power damage threshold, also in the UV
Environmentally and thermally stable
High diffraction efficiency
Available for 1030-1064 nm and 800 nm – or custom wavelengths
Low wavefront distortion
Low stray light

Products

We produce pulse compression gratings to custom specifications, but also offer the below grating types as standard products. All our gratings are high energy/power capable.
