Tunable picosecond laser

NKT SuperK Extreme is a fiber turn-key supercontinuum laser designed for spectroscopic application delivering a tunable spectrum between 450nm and 2400 nm at 78 MHz repetition rate. Coupled with a variable full automatic filter (SuperK Varia), the visible bandwidth (450-800 nm) can be  reduce to few nanometers, choosing in the same time the central wavelength.

  Specification:

- repetiotion rate: 78 MHz

- polarization: unpolarized

- beam output: gaussian, single mode

- total power: 2W

Applications:

- optical spectroscopy

- plasmonic structures characterisation

- optical metrology

- high speed Tomography and Profilometry
