Subject: Re: Purple Beamed Laser Pointer


On ebay, your search keyword is 405nM.

I think Blu-ray DVD players use 405nM violet lasers. Mass production
makes them cheap: $3 for cheapest violet laser pointers. (Makes zinc
sulfide glow quite brightly!)

Or for hundreds of milliwatts and burning some holes, use search terms:
405nm laser module
