TOPTICA’s new frequency comb DFC is the ultimate choice for ultra-precise measurements and frequency referencing.
New products to be shown at the Moscone Center in San Francisco from February 13th – 18th 2016 include ultra-stable diode lasers and powerful femtosecond fiber lasers, as well as frequency combs and terahertz systems. These systems enable a variety of demanding applications in biophotonics and microscopy, materials and test & measurement, in addition to quantum optics and spectroscopy.
Low-noise frequency combs with record stability
TOPTICA’s frequency comb DFC-CORE is the ultimate reference for optical frequencies and it convinces with completely new technology compared to previous systems. The DFC is now available in a compact one-box format including electronics. The fiber-based system uses difference frequency generation (DFG) to create an offset-free output at 1550 nm, and no active stabilization of the offset frequency is necessary. Due to this rock-solid passive operation, the DFC-CORE achieves an unprecedented low phase noise of less than 32 mrad in a spectral interferometry measurement. Consequently, when locked to an RF reference, its high stability results in an unrivaled deviation of less than 1x10-13 in one second. The DFC-CORE allows for complete frequency-stabilized laser systems, including the frequency comb, wavelength extensions and diode lasers referenced to the comb.
