This “Homemade Lightsaber” Is As Close As You’re Gonna Get To The Real Thing

Even if you don’t like Star Wars, you have to admit that lightsabers are awesome. The expanded universe sought to explain lightsabers as pseudo-magic crystals that emit light beams, but it really is just a powerful laser.

That powerful laser has now been made by YouTube user styropyro. It’s a 3000mW laser that can burn through a number of flammable objects. Check it out:

Here’s how he built it:

This laser uses the new 9mm 450nm laser diode and runs on two 18650 Li Ion batteries. The housing is a custom machined “Sirius” host. I usually try to refrain from using the term “lightsaber” when referring to my lasers but there really isn’t much else out there to describe this laser.

To be honest I don’t even like handheld lasers this strong, but I knew my subscribers would like this! This laser is legal to own in the US, and I wore goggles while shooting this video.

He reiterates that the laser in the video is completely legal in the U.S.

    What kind of substrate did you use to transmit the laser? Was it pumped through laser glass or a crystal of some sort like YAG?
