Abstract: We show that the recently implemented single-shot transverse autocorrelation technique (TAC), which takes advantage of the second-harmonic light generated in transverse direction by a random nonlinear crystal and was shown to work for light pulses of 200 fs, can be extended to measure pulse duration and initial chirp of pulses with durations down to 30fs. This technique can be very useful for easy in-situ inspection of ultrashort light pulses.
