From quanta to quasars

Lasers are used to improve the accuracy of measurements, from time to space. Lasers also improve precision in manufacturing, where the heat from the focused beam results in smoother surfaces. Light-based devices are helping to transform manufacturing of electronics, computer chips, lenses, windows and mirrors.


Height of Light

Lasers and light technologies help solve the mystery of the missing professor, and help us study diseases, forests, and even art. Find out how lasers figure in the work of Waterman awardee Andrea Alù, Margaret Murnane, and other prominent researchers.
