The sales increase and streamlining efforts saw Coherent swing to a pre-tax profit of $9.9 million in the latest quarter, ...

Coherent is the world's largest optical, laser, and photonics company. Click here to find out why I rate COHR stock as a buy.

An old optical drive tray acts to move the laser-wielding sled while a stripped ... For the right side, where coherent light is measured, to borrow a Rolling Stones lyric: no colors anymore ...

Complex organic-dye molecules have been induced to emit coherent laser light. The most remarkable feature of this new type of laser is that each can be tuned continuously over a range of wavelengths ...

The technique uses special cold plates made of ultrapure gallium arsenide (GaAs) that cool down when they receive focused beams of coherent laser light of a certain wavelength. Rather than heating ...

Figure B1 shows imaging of a test sample using 13 nm coherent light. A resolution of 92 nm is obtained, limited only by the flux of the EUV source. Higher repetition rate ultrafast lasers ...

Designs and manufactures solid-state lasers for science and industry. The Evolution, Spitfire, and Hurricane have established Positive Light as the leader in ultrafast and pulsed diode-pumped lasers.

The first step in obtaining a conventional holographic image entails splitting the incident coherent laser light source into a reference beam and an object beam (Fig. 1). Whereas the reference ...

Typically, lasers work by stimulating electrons in various atoms to oscillate in the same pattern. When this happens, the electrons move to a low-energy state and release coherent light ...

Lasers are known for the monochromatic nature of their light, so much so that you might never have thought there could be such a thing as a white laser. But in the weird world of physics ...
