    "abstract": "We analyze the alignment of molecules generated by a pair of crossed\nultra-short pump pulses of different polarizations by a technique based on the\ninduced time-dependent gratings. Parallel polarizations yield an intensity\ngrating, while perpendicular polarizations induce a polarization grating. We\nshow that both configurations can be interpreted at moderate intensity as an\nalignment induced by a single polarized pump pulse. The advantage of the\nperpendicular polarizations is to give a signal of alignment that is free from\nthe plasma contribution. Experiments on femtosecond transient gratings with\naligned molecules were performed in CO2 at room temperature in a static cell\nand at 30 K in a molecular expansion jet.",
