This movie shows my new lab laser in action. It runs close to 240mW presumably. It's good at burning stuff! I see the code is still present at the end of the movie. Check my other movie "Nexus laser in action" to see what it is for.

  • IR filters?

  • Yes, IR light is filtered.

  • song name please?

  • Jesselyn - Contact.

  • it's 240 mW, why do you still use a external lens to burn matches or paper?

  • Correct ixfd64! The initial beam diameter is for some things too big for burning. However whitout external lense I can still burn a lot and the hole is also bigger. It's all about irradiance like explained.

  • What country are u in ??? Is that legal

  • @conciel8. GIVE UP PORN!!!!! NOOOOOOOOOOOO!!!!!!!!!!! Wait. Is there some in heaven?

  • @Pr3miuM You could put an eye out with those things.

  • @HoorayforOranges Hi.. man, I forgot all about this video. I wonder why noone watches/comments. There is actually a teeny bit of divergence you can't get rid of. You can get very close, but no real laser has zero divergence. Diode lasers usually have huge divergence, like 60° or more; the optics are just carefully focused to make the beam as straight as possible. Some people want their lasers without a collimator since they are going to run it through optics anyway; it just adds more loss.

  • @stickyfox Wait. Laser light utilizes a polarized parallel wavefront, which is a coherent waveform of energy. It isn't divergent in the slightest.

  • 240mW green zero IR

  • A lot of people seem to think a laser is "lame" if it needs to be focused to a point to burn/pop/etc. Tip from a Real Science Guy: All lasers are divergent, meaning that over distance they spread out, reducing their energy density. You have to focus any laser to a point to benefit from its destructive power. Also, in real lab apparatus, we deliberately spread out the beam so that it won't damage mirrors and optics and so that a tiny speck of dust can't knock the whole beam out.

  • it is not so powerful sin u use magnifiers and it can ONLY pop up black balloons
