RUBY LASER PIERCES A SAPPHIRE CRYSTAL — A pulsed ruby laser piercing a sapphire crystal is shown on this week’s front cover. The laser at the Radio Corporation of America Laboratories in Princeton, ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This is a ruby crystal from Theodore ...

IN a cavity laser system, oscillation by stimulated emission occurs when the gain is sufficient to overcome the total loss in the cavity. Cavity loss not only determines the threshold condition of ...

'Laser' is an acronym for 'light amplification by the stimulation emission of radiation'. Its theoretical basis was postulated by Albert Einstein. The first tooth exposed to laser light was in 1960.

The laser weapon designed to produce maximum pain has been abandoned by the Pentagon. Or maybe it's around, playing a whole new role as a drone killer. The Pulsed Energy Projectile (PEP) is an ...

Proposers are sought for the development of ultrafast laser science applications, including microwave generation, optical time-transfer, laser-driven secondary radiation generation and attosecond ...

If there’s one lesson to be learned from [Aled Cuda]’s pulsed laser driver, it’s that you can treat the current limits on electronic components as a suggestion if the current duration is measured in ...

Chemical catalysts are the change agents behind the production of just about everything we use in our daily lives, from plastics to prescription drugs. When the right catalysts are mixed with the ...

Leik Myrabo is an aerospace engineering professor at Rensselaer Polytechnic Institute who has demonstrated the feasibility of using ground-based lasers to propel objects into orbit; possibly reducing ...

DPSS pulsed Q-switched lasers with laser radiation at 266 nm, 351 nm, 355 nm, 532 nm, 1053 nm, 1064 nm: complete laser systems and industrial model GARNET for OEM Pulsed Q-switched lasers features: * ...

Since first invented, the effort to make lasers that can produce shorter and more powerful pulses of light has been a very active one. One driving force is that if you want to take a picture of ...
