In which fields are lasers applied?

Lasers have a wide range of applications across various industries, making them indispensable in modern technology. The correct answer highlights some of the most prominent uses of lasers.

In the medical field, lasers are frequently utilized for procedures such as laser surgery, dermatological treatments, and eye corrections like LASIK. Their precision allows for minimal invasiveness and improved recovery times.

Telecommunications relies heavily on laser technology for fiber-optic communication. Lasers transmit data at high speeds over long distances through optical fibers, facilitating reliable and fast internet and telecommunications services.

In manufacturing, lasers are used for cutting, welding, and engraving materials. Their ability to focus on fine details allows for high precision in manufacturing processes, improving efficiency and quality.

While lasers are indeed used in astronomy and entertainment, and even in photography, focusing solely on those areas would not provide a comprehensive view of their vast applicability. Additionally, the suggestion that lasers are used only in areas of science without practical applications is incorrect, as lasers have a significant impact on numerous practical, real-world applications across various sectors.
