1. They used a pulsed optical laser , where each pulse consisted of exactly 532, 361 oscillations. 2. In principle, a clock tuned to the higher frequencies of optical lasers would be even more accurate. 3. It is NASA's first attempt at two-way space communication using an optical laser instead of radio waves. 4. An optical laser works by sending out a very narrow beam of photons ( light elements ), 5. The search for optical laser transmissions is carried out by the Automated Planet Finder of Lick Observatory. 6. When using optical lasers , there is a distinction made between " direct drive " and " indirect drive " systems. 7. Optical lasers record the information, but we know this system better as CD-R ( CD-recordable ) and CD-RW ( CD-rewriteable ) technology.8. The current developmental stage of the atom laser is analogous to that of the optical laser during its discovery in the 1960s. 9. Masers spread out more rapidly than optical lasers owing to their longer wavelength, and so would not have as great an effective range. 10. It took more than a decade to find practical uses for optical lasers , now ubiquitous in CD players, supermarket scanners and operating rooms.
