The normalized vector potential a0 decreases to 1.85 for the 0.5-mm jet and 1.67 for the 1-mm jet. (c)-(d) Spectra of the reflected laser pulses for the 0.5-mm jet (c) and the 1-mm jet (d), with photon energies of 1.5 eV (0.5-mm jet) and 1.46 eV (1-mm jet). The FWHM bandwidths for the two cases are 10.1% (0.5-mm jet) and 10.6% (1-mm jet).
