Lasers!

In fiction, we see lasers blow up planets in sci-fi tales or guard precious gems in spy movies. But over the last 60 years, lasers have become a real and important part of science, technology, and medicine. This includes physics, where lasers are used to study everything from black holes in the cosmos to particles on the quantum scale. But what even is a laser? In this talk, we’ll explore what a laser is, how they work, and how we use them to learn more about the universe around us.
