Difference Frequency Comb (DFC) - Frequenzkämme

Compact, robust, high-end and convenient TOPTICA’s frequency comb product line uses our proprietary CERO-technology which is based on Difference Frequency Generation (DFG). It is inherently fCEO-stable and combines high robustness, high-end performance and a convenient user-interface in a compact format. Frequency combs are used to measure absolute optical frequencies and to stabilize cw-lasers to specific frequencies, for example in order to drive transitions in cold atomic samples. Stabilization of Tunable Diode Lasers to a frequency comb is a reliable way forward to deal with the rising complexity of optical quantum technology applications.
