DFC Wavelength Extensions Wavelength conversion from 1560 nm to any desired wavelength between 420 and 2200 nm

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.

Your Benefits

Tailored to your needs
Modular extensions, as well as custom extensions and beat detection in DFC EXT housing available. Seamless use with TOPTICA's DFC CORE + system. 
Easy to control
Featuring independent remote control of different extensions. Up to three extensions per DFC EXT. 
Reliable operation with maximum uptime
To minimize downtime, all pump modules are field-replaceable. In the rare event of a pump diode failure, a replacement module will be shipped by express delivery and exchanged on-site by TOPTICA or by your trained staff with remote support. This eliminates the need to return the system for repair. 
In-field upgrade of wavelengths
If your requirements chance, the DFC easily changes with them. Benefit from our in-field upgrade of new wavelength extensions.
