lasers

I saw this article with a demo of a light display that creates points of light at particular points in space. http://www.thisiscolossal.com/2014/11/an-aerial-laser-display-capable-of-projecting-3d-objects-in-mid-air/ This is just the same youtube that is in the article: GNoOiXkXmYQ Anyone...

My son is thinking of adopting a kitten that had a baby gate fall on it, injuring its back. Its walking again and able to climb in and out of its litter box. The adoption agency said it has been getting cold laser therapy for the injury. My brief research seems to imply its bunk. But my son...

I thought the fastest way to get a real answer to this question, including the follow-on ramifications, was to post here and let the resident science guys get to work. Suppose you wanted to look at a small opening sealed with ice--would using a laser pointer cause melting? Are some colors more...

If anyone else started a thread on this I apologize, but I would like to read opinions from forum members on the following article: http://optics.org/news/3/1/37 If the NIF is claiming a "burn" within the next 18 months then this would be the biggest news in the energy world since Fermi made...

Is this thing for real? I mean, can you really homebrew something like this? yTnqamZJ97g I have to get my hands on one of these. :D

Hi everyone, I'm hoping someone can point me to some good links about the process of using lasers to stop smoking. A friend of mine is talking about getting it done and I immediately thought "bullsh*t" as soon as she told me a laser could stop her from smoking.. I'd really like to show her some...

China has beamed a ground-based laser at U.S. spy satellites over its territory, a U.S. agency said, in an action that exposed the potential vulnerability of space systems that provide crucial data to American troops and consumers around the world. The Defense Department remains tight-lipped...

Ugh http://news.yahoo.com/news?tmpl=story&u=/ap/20050309/ap_on_re_us/religion_prize Where do I start: 1) I don't have to have faith in gravity. I fall down a lot. 2) I don't have to have faith in heat conduction to burn the crap out of my hand on a stove. etc. I don't care if a...

I recently "charged" some glow-in-the-dark material and then shined a laser pointer on one part of it. After only a few seconds, I removed the laser light and noticed that the targeted part glowed considerably less than the rest of the material. Why?
