Picosecond pulse of laser light

One of the fastest events yet photographed - a picosecond pulse of laser light - is shown above. The photographic technique was described recently by researchers at Bell Telephone Laboratories. Typical tracks and the corresponding photodensitometer traces are shown in parts (a) and (b). The photodensitometer traces indicate relative bright and dark areas on the photo. The fluorescing spot, indicating the overlap of 0.53 micron and 1.05 micron wave-length pulses, is seen near the right end of each photo. The background trace on (a) was produced when the 0.53 micron pulse was decreased and the intensity of the 1.06 micron pulse was proportionately increased so that the background trace disappeared. The fluorescing spot is clearly visible., Credit Line: Bell Laboratories / Alcatel-Lucent USA Inc., courtesy AIP Emilio Segrè Visual Archives, Physics Today Collection
