| Abstract: | Abstract Phase-matching techniques are widely used to retrieve nonlinear optical signals of electronic and vibrational transitions. Here, collinear, phase cycled pulses are used to collect the same nonlinear signals in direct analogy to nuclear magnetic resonance studies. An acousto-optic pulse shaper is used to create suitable sequences of ultrashort pulses with arbitrary relative delays and phases. The rapid update rate of the acousto-optic modulator allows for impressive data rates. |
