First Laser Operation Occurred May 16, 1960

Why this is here: Theodore Maiman constructed the first working laser from a pink synthetic ruby crystal, initiating a technology that now supports high-speed internet and advanced medical treatments.

The United Nations Educational, Scientific and Cultural Organization (UNESCO) commemorates the International Day of Light each May 16th. UNESCO proclaimed this day in 2017 to recognize light’s importance to science, sustainability, and education worldwide. The date marks the first successful operation of a laser, achieved on May 16, 1960, by American physicist Theodore Maiman.

Maiman built the first functional laser using a pink synthetic ruby crystal and a flash lamp. This experiment produced a coherent, monochromatic beam of light. His work at Stanford University earned him nominations for the Nobel Prize, though he did not win.

Light studies now underpin medical tools, specialized treatments, and high-speed fiber optic internet. In Mexico, the UNAM’s Museum of Light in Mérida hosts lectures and workshops. The article does not detail future research directions or ongoing challenges in light-based technologies, leaving room for continued innovation.
