Hey everyone! :) I was surfing the web when I found out that Sanwu sells G2 lenses. I was surprised by the fact that they sell them for 10 bucks! This is a lot cheaper than anywhere else I've searched. For example, DTR is selling them for 30 bucks and SurvivalLaser for nearly $45 (both with a...

Hello people. I made this thread because I'm seeking for help regarding building my first laser. I've been reading a lot about lasers lately. I have spent hours on end (even when I should be studying for my exams, but now those are over-I think I did pretty well anyway XD ) trying to figure out...

So, this popped up in my News feed on Facebook. Sounds quite interesting, so I thought I should share it here :) We Could Have Lasers More Powerful Than Exploding Stars In Just 5 Years | IFLScience

I decided to do something different with my 100th post... I never really formally introduced myself, so here I am! Better late than never! Well, some of you may know me a bit already, but some (most) may not. I made this account back in 2013 but I wasn't intending to be really active, since...

Hey everyone, I have a question. It might appear stupid to some but I'll go ahead anyway. As you probably know already, ionization is the process when an atom is given enough energy and it loses (or gains) electrons as they get excited to higher states (eventually leaving the atom). And, as we...

Hey guys, this is my first thread/post here, so go easy on me XD (I just checked that this is actually my second one, but the first one was a long time ago and I totally forgot that I made it lol) So, I'm interested in buying a 1W 445/450nm laser pointer, but money is an issue. I found some...
