DFC Extensions
Wavelength conversion from 1560 nm to 420 - 2200 nm
• Modular extensions • For use with DFC CORE/DFC CORE+ • Upgrade at any time after purchase
• Interchangeable between outputs • All-fiber amplification, nonlinear conversion and compression
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 ultrafast 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.
Applications
• Optical Clocks • Microwave Generation • High-resolution Spectroscopy • Laser Reference
• Dual-comb Spectroscopy • Direct Frequency Comb Spectroscopy • CEP-stable Seeders
DFC example: Complete laser system for 40Ca+ spectroscopy
