Uses of laser in Everyday Life

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

• The intense heat produced in a small area by a laser beam is also used for welding and matching metals and for drilling tiny holes in the hard material.
• The precise straightness of a laser beam is also useful to surveyors for lining up equipment especially in inaccessible locations.
• It is the potential energy source for inducing fusion reaction.
• It can be used for telecommunication along optical fibers.
• The 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 a rangefinder.
• It is used for the purposes of the photographic recording of the output of a computer.
• It is used to develop hidden fingerprints.

Lasers in surgery and medicine

• Laser beams are used as the 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 the laser to study how the absence of those organelles affects the behavior of the cell.
• Finely focused the beam of the laser has been used to destroy the cancerous and pre-cancerous cell.
• The heat of the laser seals off capillaries and lymph vessels to prevent the spread of the disease.
• The laser is used to breaking the stone in the human kidney.
• It is used to develop hidden fingerprints.
• It is used to destroy the tumor.
• It is used to weld the detached retina.
