Smooth ultrashort pulse generation

Neolit seeders are novel sources of ultrashort laser pulses, free of consumable components like SESAM, which makes them exceptionally long-lasting.

The all-fiber design ensures high environmental stability against vibrations and thermal fluctuations.

The integration is very simple because of a compact single box, passively-cooled construction.

High quality temporal and spectral shape of the pulses guarantees excellent results at the output of the laser system.
