Perfect lock to optical reference
The DFC is especially suitable for use with an optical reference like a narrow linewidth laser. If stabilized to such an optical reference the frequencies of the…
Each laser pulse is travelling through the amplifier chain, non-linear fiber and DFG unit individually. This means each pulse is broadened to a super continuum individually and the Difference…
100 times faster noise reduction
DFG is taken for each pulse individually (intra-pulse DFG) All-optical phase-lock Not limited by bandwidth of electronic feedback Two orders of magnitude…

Figure 3 shows a time trace of the fringes over 25 seconds and the CEP which has been extracted by Fourier transformation. We deduce 12 mrad phase stability in 25 seconds.View all products
Figure 2 shows the ultra-low phase noise of the DFC CORE + measured according to Liehl et al. The long-term CEP stability can be characterized if the bandpass filters and balanced detection from…
