I have always been fascinated by strong lasers - the stronger, the better!
But times have changed since my most powerful laser was a <5 mW red laser pointer and I could only dream of owning something stronger.

Now, I have lasers so strong that I prefer to have their power lowered when setting them up or testing for example divergence.

In my new video, I test ideas from my viewers for lowering the power. All of them work, but which one is the best?

The tests will take us far around in the world of amateur science. I even show a lazy man's way of decarbonating cola...

COLA is PERFECT for lowering a laser's power!?!

Lasers are just getting stronger and stronger, but sometimes you want to lower the laser beam's power. For example when measuring beam divergence or setting up an optical system safely. In this video, I will test some of my viewers' suggestions for lowering a laser beam's power. Including using my favorite drink: cola! Will it work? Will it even be the best choice?

Any reason you didn't try a simple glass photographic polarising filter before heading for the variable ND? There are some pretty cheap ones available. There are Amazon basic ones for about €10.

Not really. I just went straight for the luxury edition of a variable ND. It is convenient compared to having only one polarizing filter or two separate filters. But the cheap ones could be made to work just as fine. I believe the reason for the high price of photography variable ND is the need for them to be as color neutral as possible. For lowering one laser wavelength I don't care for color neutrality across the visible spectrum... I will have to stress-test the variable ND in a future video and may order some cheap glass polarizing filters too to see how well they work and cope with high powers.

Could you calculate how much width the coke needs to darken a specific wavelength to a specific value?

Assuming all Coco-Colas or Pepsis are created equally around the world, it should be possible to make a chart showing how much 'x' cm cola will lower wavelength 'y'. It should even be possible to make a standard test to see if a given red laser pointer is under 5 mW by sending it through a given length of cola. But that involves some safety considerations and legal disclaimers to publish :) But I am considering making it. Thanks for the input!
