405nm (think black-light on crack) has a small dot (consengtrates the power ) and IMO is the best diode for engraving etc- it is also (IMHO) the most dangerous as to the uninformed they appear to not be very bright-- bad wavelength to allow kiddos to 'PLAY with' no laser is a toy-- even the red cat toy lasers. Only one really enjoying is the one holding the pointer--- cruel to make a pet chase something they can never catch.. much worse for dogs IMO.
You dont have to believe me--see what 'the dog whisperer' says--
I know he talks about lasers on his shows--but in a search I could not find much w/ the dog whisperer...on this topic...
however here are a link to search and one good one I found.

Mr Murphy at LPS.org has the very best advice concerning lasers and our pets--
Some of what he tells us may NOT make you happy--he agrees with Caesar and myself 100%--

LPS needs to be visited often--many new stuff on a regular basis--- his advice might save you from jail/prison.
He has awesome credentials . He was involved with Pangolin from the start-has been president of ILDA and does LPS as a free service...(make a donation if you like!!)--- personally I do not care if a laser gets you into trouble-- enjoy jail- AND get banned from owning any laser for life!!!
- I do, however, care about this forum and its members--EVERY time a new laser incident gets reported we get closer to a ban in USA of ALL LASERS over 5mW (portables). This has happened to many other countries.. it can happen here--

Most cats love laser pointers. You can press the button and let the red laser land in a pinpoint on the floor, or the wall...just out of reach of your cat, and...

I had a friend whose dog was badly obsessed trying to catch any bright lights he saw--- & it happened the first time the dog saw a laser-- afaik there is no way to treat this problem easily--- get off the couch and take your dogs for long walks!!
