Lasers revisited - Their superior utility for interstellar beacons, communications, and travel
Author and Affiliation:
Rather, John D. G.(NASA Washington, DC, United States)
Abstract: This paper demonstrates reasons why research supporting SETI and Communication with Extraterrestrial Intelligence should be broadened to optical wavelengths rather than focusing almost entirely upon microwave wavelengths and technologies. New perceptions regarding the feasibility of laser technologies, along with reassessments of signal-to-noise considerations, show both the desirability and feasibility of optical interstellar transmissions, especially at IR and visible wavelengths. It is shown that utilization of the large bandwidths available at optical wavelengths greatly improves the possible use of such endeavors.
