uses of laser in daily life


List of uses of laser and applications in the field of medicine,industry and agriculture

  • The intensed heat produced in small area by a laser beam is also used for welding and matching metals and for drilling tiny holes in hard material.
  • The precise straightness of a laser beam is also useful to surveyors for lining up equipment especially in inaccessible locations.
  • It is potential energy source for inducing fusion reaction.
  • It can be used for telecommunication along optical fibres.
  • Laser beam can be used to generate three-dimensional images of objects in a process called holography.
  •  A laser beam is used to drill small (tiny) holes in hard metals.
  • It is used for welding in electronic circuits.
  • It is used to induce nuclear fission reaction.
  • It is used to produce three dimensional images.
  • It is used as range finder.
  • It is used for the purposes of photographic recording of output of a computer.
  • It is used to develop hidden finger prints.

Lasers in surgery and medicine

  • Laser beams are used as surgical tool for “welding”detached retinas.
  • The narrow intense beam of the laser can be used to destroy tissue in a localized area. The organelles with a living cell have been destroyed by using laser to study how the absence of that organelles affects the behavior of the cell.
  • Finely focused the beam of laser has been used to destroy cancerous and pre-cancerous cell.
  • The heat of the laser seals off capillaries and lymph vessels to prevent spread of the disease.
  • Laser is used to break the stone in human kidney.
  • It is used to develop hidden finger prints.
  • It is used to destroy tumor.
  • It is used to weld the detached retina.
