Distribution of energy with precision

Alignment and calculation as well as imaging

There are several uses covered within these three categories. They include delivery of energy with precision during delicate surgeries, heavy duty welding, and other challenging functions; and even ordinary uses like normal alignment of house ceilings or measurements of atomic properties of substances in a laboratory setup.

Transmission of information and its processing

Laser Scanners

Tools that use lasers are very useful in the field of telecommunications and wherever processing of information is required. They have the capacity to consolidate laser beams onto a single small spot, and then keep turning those beams on and off many times; like in billions of turns in a single second.

A red beam within the laser scanner in supermarkets, for example, is scanned by a spinning mirror, as the cashiers pass the packets of merchandise around that beam.

Optical Sensor

An optical sensor detects light being discharged from those bar codes with stripes found on individual products, and every time it deciphers that unique symbol. Thereafter it sends the data reading into some other device, and that device adds the price that is relevant as per the bill.

Lasers are also used when playing music or viewing videos that have been recorded. They are also very instrumental in the reading of computer software.

Tiny semi-conductor lasers that are low in cost are used in reading data from several formats found in optical CDs or compact discs.

About the years of the 1980s, CD-ROMS, or Compact Disc Read Only Memory, as well as compact disks that were solely audio would be created using infrared lasers. That was before use of the computerized data became commonplace.

As technology improved, the lasers in use became more efficient. Optical drives of newer versions were used in recording data onto discs that were sensitive to light; like the ‘recordable’ CD-Rs and the ‘read/write’ CD-RW. One can play these two the same way one does in ordinary CD-ROM drives. This is the same way DVDs or Digital Video Disks, what are termed versatile disks, work.

Furthermore, they have capacity to read any extra tiny spots by making use of a red laser whose wavelength is shorter. This enables channeling of sufficient information by these discs, for the purpose of playing motion pictures.

Disks of the Blu-ray kind utilize blue-light lasers for reading and storing data at densities that are even higher.

Fiber-Optic Systems of Communication

Laser beams of the semi-conductor type are used networks of fiber-optic communications, for the purpose of transmitting signals for distances that are significantly long.

Optical signals are carried at infrared wavelengths that are 1.3 micro-meters to 1.6 micro-meters; these wave-lengths bearing the greatest transparency possible as far as glass fibers are concerned.

Optical fibers have great importance as elements within the networks of world communication. In fact, most of the phone calls people make across town borders partially go through these type of optical fibers.

Energy Delivery with Precision

Laser energy is utilized in the industrial sector as well. It happens to be concentrated not only in space but also time, so that it melts and burns away, and sometimes vaporizes, a big range of materials.
