100 times faster noise reduction  
URL: /technology/toptica-proprietary/cero-1/100-times-faster-noise-reduction#c22984
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…

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  
Ultra-low noise and narrow linewidth  
URL: /technology/toptica-proprietary/cero-1/ultra-low-noise-and-narrow-linewidth#c22936
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…  
Ultra-low noise and narrow linewidth  
URL: /technology/toptica-proprietary/cero-1/ultra-low-noise-and-narrow-linewidth#c22942
The carrier envelope offset frequency fCEO of the DFC CORE +  is zero because of the DFG process implemented in the CERO-Technology . Since it is hard to measure a signal at the frequency…

Perfect lock to optical reference - Perfect lock to optical reference  
URL: /technology/toptica-proprietary/cero-1/perfect-lock-to-optical-reference#c22888
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…
