NEOLIT 
Ultrashort pulse fiber seeder for laser amplifier
1020-1070 nm, 1-10 ps, 15-40 MHz, 1-50mW
Standout features:
-
No consumable components
-
Robust to external disturbances
-
Ultra high quality pulses and spectrum
-
Highly customizable output parameters
-
Ultra wide spectrum compressible down to 30 fs

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.
