Ultrashort pulse laser

Okay kiddo, so there's a special kind of light that's called a laser. It's like a flashlight in that it shines a beam of light, but it's much more powerful and bright.

Now, there's a type of laser called an ultrashort pulse laser. This means that the laser shoots out tiny bursts of light that are extremely short - like a billionth of a second short!

This type of laser is really special because it can do things that other lasers can't. For example, it can cut incredibly tiny things with incredible precision. You know how you use scissors to cut paper? Well, imagine doing that with a laser, but even smaller, like cutting a single strand of hair. That's how precise an ultrashort pulse laser can be!

Scientists also use these lasers to study really small things. You know how you use a microscope to see things that are too tiny to see with your naked eye? Well, scientists use ultrashort pulse lasers like a super-powered microscope to look at even tinier things, like atoms and molecules.

So, an ultrashort pulse laser is like a really strong flashlight that shoots out tiny bursts of light in a billionth of a second, and it's used to cut really small things with precision or study invisible things like atoms. Pretty cool, huh?
