Interesting. I haven't ever heated coffee using a laser, but I have heated coffee before using a couple kW of radio waves at approximately 2.5 GHz, which is a similar idea

Uh - Trinity --
That's called a microwave oven - though the new ones run at 5 GHz I believe. 2.5 Ghz is uplink frequency.
Damn - that sure is a nice beam

Instant coffee is evil.

I find it hard to believe that was a 2kW laser unless it was IR or UV, shouldn't the beam be clearly visible? Wether or not my concern is correct, it's bigger than most.

According to label on it - it is a Nd-YAG laser which is IR....unsure EXACTLY what wavelength it is, but it is most definitely IR.

Thats why they were zapping it with the laser to boil all of the evil (and flavor) out of the stuff.

Looks like a very cost-effective way to heat food.

Nd:YAg outputs at 1064 nM. IR but if it's powerful enough, it will ionize air. It's a neat effect when focused. Not efficient for heating food -- I don't think the efficiency is over 10%.

Now all we need is a laser toaster that can burn CPF logos onto toast. Breakfast is served!

You see it because the camera can detect infrared... the same way you can see an infrared remote with a camera.
