The Fundamentals of Laser Technology

What is a Laser?

A laser is a mechanism that uses optical amplification to produce a beam of coherent light. Gas lasers, fiber lasers, solid state lasers, dye lasers, diode lasers, and excimer lasers are among the various varieties of lasers. All of these lasers share the same common series of components.

Laser Components

1.Obtain a medium that can withstand stimulated emission.

2.An energy supply to drive the gain medium.

3.Total reflector for energy reflection

4.Participant reflector

5.Output of the laser beam

The wavelength of the laser beam and the intensity of the laser are determined by the gain medium and resonator.

How is Laser Technology Used?

Many of the things we use on a daily basis depend on lasers. Consumer devices such as Blu-Ray and DVD players use laser processing to read data from discs. Lasers are used to process data in bar code scanners. Lasers are also used in a variety of medical operations, including LASIK eye surgery. Lasers are used in manufacturing to carve, engrave, drill, and label a variety of materials.

There are many applications for laser technology including the following:

Laser Range Finding

Information Processing (DVDs and Blu-Ray)

Bar Code Readers

Laser Surgery

Holographic Imaging

Laser Spectroscopy

Laser Material Processing

    Cutting

    Engraving

    Drilling

    Marking

    Surface Modification
