How To Make a Spiral Out of Light—The Optical Vortex Experiment

In this video I show you how to make light that has orbital angular momentum and what it looks like shined on a screen ,This type of light is called spiralized light, or an optical vortex.

Get the diffraction pattern here:

The spiral light is used in microscopy to achieved superresolution (STED), going beyond the diffraction limit of the light microscope.

I'm actually doing research at my University's optics lab with optical vortices! It's very cool to see some public showcase of these as I have really only seen dense academic papers on the subject. Great video!

Next episode: opening wormholes by unfolding space fractures and how to stay safe from the time devouring monsters on the other side.
Me: Sure. Mhhm. Just a normal episode.

Did anyone else think he said “put it in a coffee machine” at 1:15 ?

Him: *Says momentum *
Me: Okay, I'm not gonna say it.
Him: *says that again a few times*
Me: WHEN THE MOMENTUM, AND THE MOMENT ARE IN RHYMEEEE GIVE ME THIS MOMEEEENT

I can't get enough of those super hi-tech simulations.

Question:

So if you will move the paper closer to the light source, the "spirals" will rotate as you move closer?

0:49 stare at the middle of the symbol and you can see a circle...

About you said at the end of the video, I not only enjoyed it, I loved it too. You've demostrated exactly how I imaginated the light could travel when I was in the school studying basic Physics and the types and physic of waves. This is one of most educative videos of Sicence I ever seen. Thank you for post it! 👍

Could you show us the spiraling by using a fog machine?
