  Space-time wave packets (STWPs) are a new class of pulsed optical beams with
many unique and intriguing attributes, including propagation invariance and
tunable group velocity in linear optical media. STWPs are a form of
spatiotemporally structured light, so their synthesis poses challenges that are
not shared by conventional monochromatic structured light fields. We present
here a detailed description of the synthesis of STWPs that are localized along
one transverse dimension and uniform along the other; i.e., space-time light
sheets. We also describe the main characterization schemes needed for
benchmarking the unique properties of space-time light sheets.
