Dispersion system

Octave spanning GDD management
High throughput
GDD matched to hollow fiber compressors
Compact prealigned housing

Minimum pre-ionization, enhanced coherence lengths and extreme temporal confinement of the high-order harmonic generation process are only a few of the benefits resulting from employing near-single-cycle driving pulses in attosecond science.

Octave spanning spectra can be reproducibly generated by coupling sub-30 fs pulses (Femtopower?) with energies in the multi-mJ range into Hollow Fiber Compressors (Kaleidoscope?). These continua can now be compressed to sub-4 fs by employing the Mosaic OS, a dispersion management module based on the most advanced dispersive mirror technology.

Octave Spanning Dispersion Management
Mosaic OS can support pulse durations below 4 fs. The employed dispersive mirrors exhibit high reflectance over a bandwidth of 600 nm between 400 nm and 1000 nm and controlled group delay dispersion (GDD) over more than one optical octave, between 450 nm and 960 nm. The dispersion of the compressor is matched to the typical chirp of pulses generated from noble-gas-filled hollow fibers seeded with sub-30 fs, mJ-level pulses. All mirrors are pre-aligned in a compact, robust housing equipped with entrance and exit aperture. Mosaic OS is the octave spanning upgrade to the current dispersive mirror set of your Kaleidoscope hollow fiber compressor.
