  • Recommend me a laser from Amazon? - Laser Pointer Forums
    Nobody knows what all the real world outputs of the mass produced low cost throw away laser pointers on Amazon sold by several resellers actually are much less what the overspec outputs are They all promote them as <5mW That being said, that most all pointers offered on Amazon are about 1 2 the price on eBay
  • Best laser for arborists | Laser Pointer Forums - Discuss Laser . . .
    A lot of cheap ebay green pointers are dpss of 532nm ( nm is nanometers that's the wavelength ) so look for 520nm or 525nm as well as direct diode Again know your local laws and use at your own risk, but don't let the laser hit anyone's face as many ebay lasers sold as 5mw are actually 40-80mw
  • Why are 473nm DPSS laser pointers so expensive?
    So I was wondering why it was so much more expensive than 5mW 532nm DPSS green laser pointers (which at the same time, and in the same catalog were still quite expensive, at about $300) And I'm also wondering if the price for 473nm 5mW laser pointers is still $500+, because I can't really find any company selling them anymore at any price period
  • What mw is required to burn paper? Pop balloons? Light match? Any . . .
    50mw of 532nm will not light a match It typically takes at least 150mw unless of course you are talking about the very cheap 50mw pointers that are actually IR pointers with 45mw of IR and 3-5mw of green
  • First build completed | Laser Pointer Forums - Discuss Laser Pointers . . .
    Also, thanks for making me spend so much on these, lol I planned to just build one to have as a cool thing, but now I have 2 serious lasers ( this and one from jlasers), 2 cheap pointers from ebay, 2 pointers I'm building up, and a plans for a high power green and blue Oh well, it's fun
  • Laser Pointer Forums - Discuss Laser Pointers | High Power Lasers
    An elite Buy, Sell, Trade section for laser laser pointer experts New threads require approval of community and or administrator Anyone may reply to posts Proven and highly respected community members can create new threads for buying, selling, trading of lasers laser pointers
  • Any way to get more than 5mw in USA? - Laser Pointer Forums
    There are some outlets that supply laser pointers over 5mW to US customers, but they are still illegal to operate without a variance Allowing the possession of OEM lasers allows educational users, laboratories, and responsible hobbyists to use lasers for research, experimentation, holography and much more
  • JLasers - NUBM0G | Laser Pointer Forums - Discuss Laser Pointers | High . . .
    I absolutely like the way you test new diodes and when you use a power meter and spectrometer for building laser pointers That will help you to make sure for instance that a 488nm laser you build will be exactly true 488nm cyan color, not 490nm or 485 nm since these wavelengths are not true cyan
  • Shape at point of impact - Laser Pointer Forums
    Cheap red pointers will usually have a "messy" dot Green laser pointers should have a nearly perfect circle The red pointers you have been using are diode lasers That is, the beam is produced by applying current through a tiny semiconductor almost like an LED There are imperfections in the "chip" that cause the beam to look the way it does
  • Anti cockroach laser device | Laser Pointer Forums - Discuss Laser . . .
    Also laser pointers are not to the point of the "laser gun" There is no point and shoot You'd need major power for a quick enough burn, and that would be way to dangerous for indoors They have a new roach compound now It doesnt kill them, but sterilizes them so they cannot reproduce It works extremely well, and lasts a long time
