[Jerry] missed the laser cutters he had been using at the local TechShop. It closed down and after seeing some hardware in a surplus store he decided to build a laser cutter to call his own.

The objective of the research in the atomic and molecular laser spectroscopy laboratory is to gain knowledge about the basic properties of ions and neutral atoms and molecules, with a particular ...

Inspired by techniques used in industry, [Les] eventually tried to use a several-kW nitrogen laser to burn off the ... aren’t just for examining light spectra—they can also be used to judge ...

The Series 3500 UV lasers from DPSS Lasers (Santa Clara, California, USA) are quasi-continuous-wave (quasi-CW) lasers with a repetition rate greater than 100 kHz.

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

How quantum physics could help lasers perform better in fog and aid communications A team of researchers at Washington University in St. Louis has drawn on quantum physics to develop a new ...

Earlier this year the U.S. Army shot down a number of hostile drones in the Middle East using a weapon long dismissed as more science fiction than reality—the laser. After decades of costly ...

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...

If you need high-quality printing in a snap, a laser printer can produce clean, sharp prints in as little as a few seconds. But, after three weeks of testing each device, not all laser printers ...

who joined Alger in 1999 and runs Alger Capital Appreciation and Alger Spectra. Alger has stuck with its growth-oriented philosophy and has taken steps to strengthen its product lineup.

The smartwatch world is crowded, but the ones at the top tower far above the rest of the competition. Few smartwatches released in the past several years have reached the level of success found by ...
