YOUR KEY to innovation and success

UltraFast Innovations (UFI®) provides spectral filters for ultrashort pulse applications – for example, for preserving the pulse duration of reflected or transmitted pulses.

By using such spectral filters, researchers from Prof. Krausz’s group were able to build a so-called wave synthesizer. We were able to split or combine radiation from 250 to 1100 nm in four channels: 250–290, 290–350, 350–500, and 500–1100 nm. The phases of reflection and transmission are controlled. This allows one to precisely combine radiation from four channels, both spatially and temporally, resulting in the generation of sub-optical-cycle pulses. Based on that technology, we have developed the first commercial light field synthesizer.

Optical components at better price
