“…The pulse duration from Fourier transformation (FT) of the spectrum is much shorter than the measured one due to the assumption of zero phase difference, but the shape is closer to the secant function, as shown in Figure 5(b). With the measured pulse duration of 23 fs for a sech 2 pulse shape, the value of the time-bandwidth product ∆t∆ν is 0.576, indicating that the laser pulse is not bandwidthlimited [16]. The diverging image of the SH signal observed in the CCD located 25 or 30 cm from the crystal could be evidence of positive chirp [17].…”

An all-reflective, simple noncollinear second harmonic (SH) autocorrelator is described for monitoring the shot-to-shot behavior of ultrashort high-power laser pulses. Two mirrors are used for the dispersion-free splitting of a pulse into two halves. One of the mirrors is able to adjust the delay time and angle between two halves of the laser pulse in a nonlinear crystal. We present the possibility of real-time measurement of the pulse duration, peak intensity (or energy), and the pointing jitters of a laser pulse, by analyzing the spatial profile of the SH autocorrelation signal measured by a CCD camera. The measurement of the shot-to-shot variation of those parameters will be important for the detailed characterization of laser accelerated electrons or protons.

“…Although this condition is not strictly fulfilled in our experiment, we have maintained the interaction angle small enough to make this disturbance negligible. However, a temporal chirp in the object pulse could give rise to a spatial phase distortion of the SF wavefront (32). Although this does not affect the results obtained with the confocal configuration (see Fig.…”

We exploit a slightly non-collinear second-harmonic cross-correlation scheme to map the 3D space–time intensity distribution of an unknown complex-shaped ultrashort optical pulse, down to a resolution of 10 μm in space and 200 fs in time. Moreover, we directly show that the spatial phase information is not lost in the process, thanks to the coherence of the non-linear interaction. This implies that the concept of second-harmonic holography can be employed down to the sub-picosecond time scale, and used to discuss the features of the technique in terms of the reconstructed fields
