This approach still requires a nonlinear broadening, which can cause amplitude-to-phase noise conversion affecting the stabilization effort. Since the venteon spectra are broad enough, we don’t need this technique and also require no fibres! (Except in the venteon power) The main advantage of the venteon CEP5 f-to-2f interferometer is that it needs only the wings of the spectrum as input and thus works with less than 20 mW of input average power, a really efficient approach! For the DFG approach > 15 0mW of power has to be used for the stabilization. Additionally, the venteon systems deliver much shorter pulses, so any CEP effect is much more pronounced!
