Day of Light: 60th anniversary of the laser

The invention of the laser 60 years ago has transformed science and everyday life.

Sixty years after the first laser was operated on 16 May 1960 by Theodore Maiman at Hughes Research Laboratories in California, lasers have revolutionized everyday life as well as science. Lasers are also fundamental for research at the European XFEL. A public event on the European XFEL campus planned to celebrate this anniversary has been postponed to a later date.

When the world’s biggest X-ray laser and one of the planet’s brightest light sources, the European XFEL, started operation in 2017, it was the culmination of several decades of scientific progress in laser and X-ray laser technology. Lasers operating in the visible wavelength range were invented in the 1960s. In these lasers, radiation is generated from electron transitions in atoms or molecules. The light emitted is then continuously amplified between mirrors. This makes it comparatively easy to produce high-quality laser light, and many applications now shape our everyday lives. Examples range from impressive light installations, to high precision surgical instruments, broadband telecommunication, components in the electrical devices we carry in our pockets, and the laser pointer we use during presentations.
