Laser SETI

Until now, SETI experiments (Search for Extraterrestrial Intelligence), whether listening for a radio transmitter or searching for a high-powered laser, have assumed that ET is on-the-air all the time, so that wherever the instrument is pointed, the signal will be there. Laser SETI is the first experiment to circumvent this assumption.

Laser SETI could find a very short ping from anywhere on the night sky. Indeed, it could detect a laser flash as short as a millisecond or less; and one that might not repeat for days, weeks, or even longer. Or ever.

Searching all-the-sky all-the-time is an essential capability when looking for intermittent signals. Radio experiments will someday be able to do that, but Laser SETI can do so right now–with your help.
