aSynopsis.-The phenomenon of dancing cables is discussed; the merits of different theories are considered, reference being made to the theory that vibrations of small amplitude, but relatively high frequency, travel along the line to points where the constants of the line change as at dead-...
When a document is sent to the printer, a laser beam "draws" the document on a selenium-coated drum using electrical charges. The drum is then rolled in toner, a dry powder type of ink that adheres to the charged image on the drum. The toner is transferred onto a piece of paper an...
The bottom of each sensor housing features a laser-engraved grid to aid in aligning and focusing the beam. In standard microscopes, this grid can be used for beam alignment before flipping the sensor head to face the objective for power measurements. In inverted microscopes, turn on the transmi...
Laser machines can also process a variety of materials like Polyimide (Kapton), Polyimide (Cirlex),Q-pad, andGrafoil. Processing those materials using lasers can add huge value to the overall supply chain for the semiconductor industry.
Customizing the output beam shape from a laser invariably involves specialized optical elements in the form of apertures, diffractive optics and free-form mirrors. Such optics require considerable design and fabrication effort and suffer from the further disadvantage of being immutably connected to the ...

Particle accelerators are used in a wide variety of fields, ranging from medicine and biology to high-energy physics. The accelerating fields in conventional accelerators are limited to a few tens of MeV m-1, owing to material breakdown at the walls o
Thorlabs' CO2Laser Line Mirrors are specifically designed for use with high-power CW lasers. These mirrors consist of an electroplated gold coating on a solid copper substrate, with a nickel layer that acts as a diffusion barrier between the gold and copper. The gold coating provides high reflec...
The first person to imagine something like a laser was Albert Einstein in 1917. He realized that it might be possible to create a very strong, bright beam of light by changing the way light acted. However, he never thought about this idea any further and neither he nor anyone else tried...
