Lasers & the Human Eye
Accidental exposure to a single direct or reflected laser beam can cause irreversible damage to the human eye—depending on the wavelength, output and exposure duration.
Looking Back—and Ahead—at the Laser Market
For laser and optics companies, revenues and net income continue to climb, but soft stock prices reflect widespread investor uncertainty.
Toward Programmable Microscopes
At FiO LS 2022, physicist Monika Ritsch-Marte will talk about using spatial light modulators to enable customizable views and deep tissue imaging.
Art and Light in Ukraine
After a brief interruption, Mykola Kabluka and his team at Ukraine-based Expolight are once again finding a way forward with light.
Making Lasers Tunable
Since the laser’s first demonstration in 1960, scientists have worked to expand the range of wavelengths the devices can emit.
