Holiday laser pulses

Each image shows the "snapshot" of a highly structured, half-millimeter-wide laser pulse moving from left to right at the speed of light. The vertical axis is in arbitrary units; the horizonal axis is in picoseconds (10-12 seconds), which refers to the time when that part of the pulse arrived at the detector.
