A laser is not just light; it is light disciplined, sharpened, and focused into a beam so pure and precise that it can travel across the Moon, cut through steel, perform delicate eye surgery, or carry billions of internet messages in a single second.
Medical Xpress: New record: Laser for surgery cuts bone deeper than before
Lasers cut precisely and without contact—ideal for surgery. The problem is that in hard tissues such as bone, they are too slow and do not cut deep enough. Researchers at the University of Basel have ...
Medical Xpress: Flexible optical fiber technology can improve laser surgery for voice box tumors
Flexible optical fiber technology can improve laser surgery for voice box tumors
Optics: University of Basel optimizes laser cutting of bone for faster surgery
Laser bone cutting, or osteotomy, is a potentially attractive route to precise removal of bone during surgery, but clinical translation remains limited by slower cutting speeds and ablation depths ...
While you enjoy your retirement, we hope you stay connected with LASERS. Explore this section and the menu options to find the tools you need to manage your account and stay informed about your retirement.
Today’s surgeons use advanced tools and techniques to perform many procedures without large cuts. But some situations still call for open surgery, especially when speed, access or complexity matters most. Surgery is how surgeons fix or explore problems inside your body.
Ferda Canbaz demonstrates the depth of cuts that can be achieved with lasers when the energy profile of the laser beam is adjusted. Lasers cut precisely and without contact – ideal for surgery. The ...
A laser differs from other sources of light in that it emits light that is coherent. Spatial coherence allows a laser to be focused to a tight spot, enabling uses such as optical communication, [6] laser cutting, and lithography.

Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths.
The most powerful laser designed to date can be found at the European Extreme Light Infrastructure facility in Romania. Its lasers are some of the most intense in the world, generating insanely brief pulses of photons, protons, neutrons, and neutrinos with incredible energy.
The word “laser” is an acronym for “light amplification by stimulated emission of radiation.” Lasers have many uses, including cutting and welding materials, measuring distance, and treating medical conditions.
An easy-to-understand explanation of how lasers work, with a simple diagram showing what's inside a laser.
How do lasers work? | Who invented the laser? - Explain that Stuff
A laser is created when electrons in the atoms in optical materials like glass, crystal, or gas absorb the energy from an electrical current or a light. That extra energy “excites” the electrons enough to move from a lower-energy orbit to a higher-energy orbit around the atom’s nucleus.
What is a Laser? The Light That Changed Science, Technology, and ...
Lasers can be used for a variety of applications. Learn how lasers work, different elements, and the differences between laser types at Edmund Optics.
Because laser light stays focused and does not spread out much (like a flashlight would), laser beams can travel very long distances. They can also concentrate a lot of energy on a very small area.
