Using other stabilisation, approaches a signal-to-noise ratio (SNR) of the beat signal of > 40 dB has been achieved? What about the SNR in the venteon CEP5 approach?

A SNR of >30 dB (@ 100 kHz detection bandwidth) for the beat signal is the standard specification of our systems, as well as typically that by other manufacturers. The venteon octave spanning oscillator typically delivers >40 dB SNR for the beat node from the interferometer (@ 100 kHz detection bandwidth) – venteon works in close collaboration with Menlo Systems for the CEP stabilisation and their locking electronic works very well with the power levels and SNR provided by the venteon interferometer.
