A laser is like a super powerful flashlight. Imagine a flashlight that can shine its light in a perfectly straight line, without spreading out. This makes the light very strong and focused, like a superhero with a special power.

Think of a laser as a team of tiny light soldiers all marching in the same direction. When they move together, they become very powerful and can do amazing things like cutting through metal or helping doctors fix your eyes.

Another way to think about a laser is like a magic pen that can draw with light. It can make very precise lines and shapes because its light doesn’t get messy or blurry. This is why lasers are used in cool things like laser shows and in machines that make tiny computer parts.

Finally, a laser is like a rainbow that only shows one color. Instead of having many colors mixed together, a laser light is just one pure color, which is why it looks so bright and special.
