Abstract
We numerically characterize visible-to-infrared pulses with durations down to 2.3 fs (0.88 cycle) by cross-correlation sonogram using a 20-μm-thick BBO crystal. This method is simple, sensitive, and potentially applicable to even shorter pulses.

We numerically demonstrated that the cross-correlation sonogram can measure visible-to-infrared pulse with duration down to 2.3 fs (0.88 cycle) by using a 20-m-thick BBO crystal, which is made possible by spectrally multiplexed nonlinear conversion (a divide and conquer strategy). The all-optical method is simple, sensitive, and applicable to even shorter pulses if narrower filter function or thinner crystal is used. The measurable pulse width will be limited by available thickness or absorption of the nonlinear crystal.
