  • 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
  • Green laser IR filter | Laser Pointer Forums - Discuss Laser Pointers . . .
    These Chinese pointers never have a filter in them and the parts that you show are glued together the 808 nm laser is soldered to the driver board, next to it is the lens to focus beam on ND:YVO4 KTiOPO4 crystals that are in the center of the of the disk in the next picture, they will change the output of the 808 nm to 1064 nm at about 60% of

    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
  • Difference Between Red And Green Laser?
    Thanks for the great info you two, the only thing I am concerned about is the price of the lasers on the websites you advised me to go to especially when it comes to the 200-300mw laser pointers red or green in colour, the cheapest one I could find was £380 92 ($679 00)

  • 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
  • Pot modding FAQs | Laser Pointer Forums - Discuss Laser Pointers . . .
    (For those of you reading this thread out of serious curiosity, the vast majority of laser pointers available on the open market now are operating at or near the output limit of the laser diode, so putting more power into the diode by adjusting the potentiometer will -- more likely than not -- just burn your laser out
  • 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
