In 1960 physicist Theodore Maiman constructed the first working laser.This design was improved upon Bell Telephone Laboratories in 1961.Since then lasers has been found to have a wide variety of applications.Identify one application of laser technology and explain how this application has impacted society.
How about DVD players?

One application of laser technology is laser surgery. Laser surgery is a medical procedure that utilizes focused beams of light to precisely cut, vaporize, or coagulate tissues. This technology has had a profound impact on society in several ways.
To understand how laser surgery works, it is important to note that lasers emit a concentrated beam of light that can be precisely controlled. In surgical settings, this precision enables surgeons to target specific tissues and perform delicate procedures with minimal damage to surrounding healthy tissues.
Laser surgery has revolutionized various medical procedures, making them less invasive, reducing the risk of complications, and improving patient outcomes. For instance, in ophthalmology, lasers are used to correct vision problems such as nearsightedness, farsightedness, and astigmatism through LASIK surgery. This procedure has allowed millions of people worldwide to reduce or eliminate their dependence on glasses or contact lenses, greatly improving their quality of life.
In dermatology, lasers are employed to treat numerous conditions such as birthmarks, scars, wrinkles, and even certain types of skin cancer. Laser skin resurfacing procedures help smooth out wrinkles, improve skin texture, and reduce age spots, yielding a more youthful appearance for patients.
Furthermore, laser surgery has been widely applied in minimally invasive procedures such as endoscopy, where lasers are used to remove or ablate abnormal tissues or tumors in the gastrointestinal tract, respiratory system, or urinary system. These minimally invasive techniques have shorter recovery times, reduced pain, and fewer post-operative complications compared to traditional open surgeries.
Overall, laser surgery's precise and targeted nature has made it a valuable tool in various medical specialties. It has not only improved patient outcomes but also reduced hospital stays, decreased post-operative pain, and minimized scarring. By enabling less invasive procedures, laser surgery has impacted society by improving the overall well-being of countless individuals, enhancing their confidence, and allowing them to live healthier, more comfortable lives.
