What is Laser Ultrashort Pulse?

Laser Ultrashort Pulse is a general name for any type of laser that produces the pulses or rupture of coherent light in extremely short time periods, usually measured in picoseconds or femtoseconds. Picosecunda is one trillion of a second and the femtosecond is 1,000 times shorter than a picosecond or one quadriliift second. These Ultrashort Pulse laser speeds allow him to overcome some degradation effects that normal non-pulsing lasers encounter. This gives them an application in military technology, data communication and medical science, such as killing viruses in the body through external laser treatment without damaging normal living tissue. This technology is leading to the creation of the Ultrashort Pulse laser in the attosecond series that should have a pulse that occurred 1,000 times faster than a femtosecond laser, or once each quintillion second. Attosecond lasers would allow scientists to monitor the movement of electrons around the atomic core in real time, which wouldIt helped in research and development of chemistry.

While early lasers were based on generating coherent light rays using ruby ​​crystals, femtosecond lasers use aluminum oxide subsidized by titanium, a type of blue -green sapphire for the first time. Typical pulse energy from such 20 femosecond lasers is about 3 nanojouls per pulse or three billion joule. Because it is an extremely small amount of energy, the beam is reinforced by an external source of radiation. Fixed materials have proven to be the best amplifiers, while YTterbium Glass is the most effective and amplifies the pulse of up to 100 jouls per square centimeter. Early experiments using dyes or necksmium: yttrium aluminum pomegranteals have increased pulse energy from 1 millionoule to 0.5 joules per square centimeter.

There are many potential applications for using Ultrashort Pulse laser. They would take communication from oPiring fibers using a light signal transmission to a new level, which would allow much more data on a pulse beam than the optical fibers are currently capable of since 2011, giving the term widely new significance. They could also be used for ablation materials from the surface and their replacement from solids to gas without adding any heat in the process, which would improve in various industrial cutting and shaping metals and composites. This technology also offers the advantage that it serves as an extremely accurate form of scalpel in medicine to remove cancer tumors or repair an optical cornea in people with failing vision.
