DFC 波長拡張モジュール
Wavelength conversion from 1560 nm to any desired wavelength between 420 and 2200 nm
- Modular extensions
- For use with DFC CORE +
- Independent remote control of different extensions
- Up to three extensions per DFC EXT
- Custom extensions and beat detection in DFC EXT housing
- replaceable pump modules for lowest downtime
- in-field upgrade of new wavelength extensions
Various extension modules are available that convert the offset-free fundamental output of the DFC CORE + from 1560 nm to any desired wavelength between 420 nm and 2200 nm. The wavelength conversion in these modules is achieved with the well-established technology of TOPTICA’s femtosecond fiber lasers. All extension modules use highly stable all-fiber amplification, nonlinear conversion and compression. The output power of all extension modules allows for phase-locking of cw lasers. Special wavelength extensions are available on request or included in TOPTICA's complete stabilized laser systems.
