What is Pulses of laser light?

Pulses of laser light are like super-fast flashes that come one after another, just like when you flick a flashlight on and off really quickly.

Imagine you have a flashlight, and instead of turning it on and off slowly, you turn it on and off in the blink of an eye, so fast that your eyes can’t follow! That’s what a laser pulse is like. A laser is like a super-focused flashlight that sends out light in one direction.

Like a Blinking Light

Think about how your mom might use a timer on the stove, it beeps, and then the heat turns off for a little while before it comes back on again. A pulse of laser light works kind of like that timer. It’s on for a very short time, then off, then on again. These quick flashes are what scientists use to do cool things, like help make tiny machines or see inside really small stuff.

Each flash is a pulse, and when they happen really fast, it's like watching the timer beep, super quick and precise!
