What is a laser and where is it generally used

A laser is a device that emits a coherent beam of light through a process of optical amplification. There are many types of lasers, including gas lasers, fiber laser heads, solid-state lasers, dye lasers, diode lasers, and excimer lasers. All of these laser types share a basic set of components.


laser parts

  1. Obtain a medium capable of sustaining stimulated emission

  2. Energy for pumping the gain medium

  3. Total reflector reflects energy

  4. partial reflector

  5. Laser beam output

  6. The gain medium and resonator determine the wavelength of the laser beam and the power of the laser.

How to use laser technology?

Lasers are key components in many of the products we use every day. Consumer products such as Blu-ray and DVD players rely on laser technology to read information from disks. Barcode scanners rely on lasers for information processing. Lasers are also used in many surgical procedures, such as LASIK eye surgery. In manufacturing, lasers are used to cut, engrave, drill and mark various materials.


Laser technology has many applications, including:

  1. Laser Ranging

  2. Information processing (DVD and Blu-ray)

  3. barcode reader

  4. laser surgery

  5. holographic imaging

  6. Laser Spectroscopy

  7. Laser Material Processing

  8. cut

  9. Sculpture

  10. drilling

  11. Marking

  12. Surface Modification
