Last week we brought you inside the kooky but wonderful Holographic Studios in New York City. While we were there, we learned a whole lot about the history of hologram technology. It's a sprawling story with many facets—and also lasers.

Holography's history traces all the way back to the 19th century and early color photographic experiments of Gabriel Lippman. But it really took shape in the mid-twentieth century, with experiments in microscopy, and eventually took off with the development of the laser.

In the video above, Jason Sapan of the Holographic Studios gives us a crash course in how the shimmering 3D images came to be. It's more fascinating than any number of not-quite-hologram Tupacs could ever hope to be. [Holographic Studios / Facebook]
