Laser science

Laser science is the study of powerful beams of light called lasers. Imagine holding a flashlight that shoots out a very strong and powerful beam of light that can cut through things. That's pretty much what a laser is, but much stronger and powerful.

Lasers are used in many different ways, such as in medical procedures to help doctors see inside our bodies or to remove things like tattoos. They are also used in CD players and barcode scanners to read information.

Lasers work by putting a bunch of tiny particles called photons together in a single beam that goes in one direction. The lasers are powered by energy, which turns the photons into light.

To make the laser light even stronger, scientists use special materials where the photons bounce back and forth, getting stronger and stronger, before they are finally released in a powerful beam.

Lasers may seem like magic, but they are actually the result of a lot of hard work and science, and they have many practical applications in our daily lives.
