Abstract

We introduce a bandwidth-unlimited, dispersion- and shear-self-calibrated, timing-jitter-free pulse measurement technique based on a quasi-linear temporal phase modulation in a gas weakly ionized by a long pump pulse. Results of a 5fs pulse characterization are reported.

Spectral blueshifting of a weak 5 fs 750 nm laser field as the result of a quasi-linear refractive index change of a Kr gas target that is being ionized by a 70 fs 390 nm pump pulse. (a) Numerical simulations, showing normalized instantaneous intensities of the blue pump pulse (peak intensity 2.5 × 10 13 W cm 2 ) and a 5 fs test pulse and the evolution of the plasma density. The linear slope indicates a constant ionization rate required to produce a 1 THz blueshift at 800 nm for a 5 - mm -long Kr target at a pressure of 2   bars . (b) Experimental spectra and the calculated magnitude of the blueshift, Ω ( ω ) . Note the good agreement between the measured (+) and calculated blueshift.

Experimental i-SPIDER setup and the explanation of the pulse sequence (circles 1 and 2). The required time separation between the pulse pair creating a spectral interferogram is obtained by a slight angular detuning of the recombining beam splitter.

Retrieved i-SPIDER data for a 5.3 fs test pulse. (a) Input interferograms and calibration routine. The spectrum detail in the left inset shows the apparent blueshift. i FT, (inverse) Fourier Transform. The FT of the low-pass-filtered time domain images serves as spectral shear calibration; the FT of the high pass recovers the spectral phase. (b) Spectral phases retrieved by i-SPIDER for a nearly transform-limited pulse and a pulse transmitted through 0.3 mm of fused silica and 1 m of air. Left inset, retrieved pulse; right inset, retrieved interferometric autocorrelation.
