Coherent Light (2)

Linac Coherent Light Source
The linac coherent light source (LCLS) produces pulses of X-rays more than a billion times brighter than the most powerful existing sources, the so-called synchrotron sources which are also based on large electron accelerators. The ultrafast X-ray pulses are used much like flashes from a high-speed strobe light, enabling scientists to take stop-motion pictures of atoms and molecules in motion, shedding light on the fundamental processes of physics, technology, and life itself.

Xenon Light
Xenon is a colorless, heavy element with atomic number 54. Xenon gas is used for light emitting devices known as Xenon light. Some of the uses of Xenon light are

• It is used in photographic flashes, stroboscopic lamps and solar simulators.
• Xenon light is also used as in arc lamps and high intensity discharge headlights.( Remember the advert of the car mentioning its xenon headlights)
• It has been used for anaesthetic purposes, although it is expensive.
• Xenon light also finds its use in plasma display for televisions.

Coherent light is useful in so many ways that scientists all over the world are keenly researching its other uses like treatment in cancer etc. Although it is a vast topic, I hope this information would be useful for you to understand what is coherent light and some of the other basic things about coherent light.
