Short Bytes: Surpassing the feat achieved by an engineer building a real-life lightsaber to kill Stormtroopers, a guy has made a household laser lightsaber which is sufficient and dangerous enough to burn down most of the flammable household things including paper, plastic cups, electric wires and much more.
There are two main limiting factors on making a homemade laser lightsaber. These are beam confinement and high energy density storage. The Li-Ion batteries have been used to power the powerful handheld lasers. Li-Ion batteries are the perfect solution to energy density storage. In terms of beam confinement, anti-reflective coated glass lens have been used to focus the beam.
It has been further explained on Styropyro YouTube channel as follows:
Looks like this guy is highly inspired by the Star Wars movies. Finally, he has managed to come up with a laser lightsaber which can destroy almost all the flammable household things. But, the precaution has to be ensured before trying to make one of its kinds.
