Advantages and Disadvantages of Laser - GeeksforGeeks (1)

Last Updated : 28 Dec, 2020


Laser term represents Light Amplification by the Stimulated Emission of Radiation. It is exceptional light emission or infrared radiation. It has following attributes or properties. Laser, a gadget that animates iotas or atoms to emanate light at specific frequencies and intensifies that light, regularly delivering an extremely thin light emission. The emanation by and large covers a very restricted scope of obvious, infrared, or bright frequencies.

Monochromatic for example comprising one frequency. This implies laser can be engaged into the more modest zone for longer distances with no decrease in the force power of the laser pillar. Coherent for example all parts are in stage. It implies laser discharges rational light. Thus, it is conceivable to utilize laser in cutting and lithography. Collimated for example all parts travel one and same way. It implies laser follow slender way over more prominent distances.

Advantages of Laser :

  1. High Data Conveying Limit –
    It has high data conveying limit and consequently is utilized in correspondence space for transmission of data.
  2. Outcome of Electro-attractive Obstruction –
    It is liberated from electro-attractive obstruction. This wonder is utilized in optical remote correspondence through free space for media transmission just as PC organizing.
  3. Less sign spillage –
    It has the least sign spillage which is the biggest advantage of Laser.
  4. Used in making Fibre Optic Links –
    Laser-based fiber optic links are light and subsequently are utilized in the fiber optic correspondence framework.
  5. Used in Clinical Field –
    It is less harmful in contrast with X-beams and henceforth broadly utilized in clinical field for therapy of malignancies. It is utilized to consume little tumors on eye surface and furthermore on tissue surface.
  6. Used for Dumping down Adversary tank –
    High power and low uniqueness of laser are utilized for thumping down the adversary tank with precise reach assurance. For this reason, neodymium and carbon dioxide laser types are utilized. Laser range locater is likewise utilized in a few guard territories for medium reach upto 10 Km.
  7. Laser is used in CDs and DVDs –
    Single laser bar can be engaged in regions more modest than 1 miniature breadth. One square miniature territory is expected to store 1 cycle of information. This aids in putting away 100 million pieces of information in one square cm. Because of this reality, the laser is being utilized in laser CDs and DVDs for information stockpiling as sound, video, archives, and so forth

Disadvantages of Laser :

  1. Costly for Patients –
    It is costly and consequently more consumption to the patients requiring laser-based medicines.
  2. Costly for specialists –
    It is expensive to keep up and henceforth more expense to specialists and clinic the executives.
  3. Increases intricacy –
    Increases intricacy and length of the treatment dependent on laser gadgets or types of gear.
  4. Less uses in Dental method –
    Lasers can not be utilized in numerous regularly performed dental methods for example to fill cavities between teeth and so on.
  5. Higher forces during the cutting cycle –
    The laser bar is fragile to deal with in the cutting cycle. The slight misstep in changing distance and temperature may prompt copying or staining of the metals. In addition, it requires higher force during the cutting cycle.
  6. Destructive –
    It is destructive to individuals and regularly consumes them during contact.

What is the greatest risk from lasers? ›

The major danger of laser light is hazards from beams entering the eye. The eye is the organ most sensitive to light. Just as a magnifying glass can be used to focus the sun and burn wood, the lens in the human eye focuses the laser beam into a tiny spot than can burn the retina.

What is the harm of laser? ›

Even moderately powered lasers can cause injury to the eye. High power lasers can also burn the skin. Some lasers are so powerful that even the diffuse reflection from a surface can be hazardous to the eye.

Is laser good or bad? ›

Using a laser could cause a serious burn or discolor your skin. After having laser treatment, you'll need to protect your skin from the sun until your skin heals. If the sun's harmful rays hit your treated skin, you can develop another scar. 5.

What are the disadvantages of laser treatment? ›

Laser therapy can result in misdirected or excessively intense burns, bleeding from the choriocapillaris, damage to macular and other ocular structures, and breaks in Bruch's membrane.

What are the disadvantages of laser level? ›

Another disadvantage of a rotary laser level is that the risk of being exposed to a laser beam is high. Since the laser beams can be projected at an angle of 360 simultaneously, your eyes and other sensitive body parts may be exposed to the laser beam dangers.

Why are lasers so useful? ›

Lasers have many uses. They are used in precision tools and can cut through diamonds or thick metal. They can also be designed to help in delicate surgeries. Lasers are used for recording and retrieving information.

What are laser weaknesses? ›

Lasers are very quick to track and shoot but are affected by atmosphere, where air molecules and dust can disipate the beam. This isn't really by much though. Another weakness is the dwell time to affect heat onto a component.

What are some disadvantages to laser measuring? ›

The downsides are that they are typically more expensive than a standard tape measure, are not good at measuring short distances that don't have a surface to reflect off and in bright light you cannot see the beam so you are guessing where it is pointing.
