FABS: Low Dispersion Femtosecond Beamsplitter
FABS: Low Dispersion Femtosecond Beamsplitter
High efficiency, low dispersion 50:50 splitting of s- or p-polarization over a 200 nm bandwidth; center wavelengths from 790 to 1550 nm. The high efficiency and excellent durability of these broadband 50:50 beamsplitters makes them superior to partially reflective metal coatings for use in ultrafast laser systems and experiments. With very low loss over a ~200 nm bandwidth and near-linear GDD, they are suitable for use with laser pulse durations > 15 fs.
