    Does anybody know why my laser suddenly started changing shapes??? And how to fix it???

    Oh I believe you on the mod hopping, but it looks like a pair of pliers were put on the aluminum tip??

    Looking for a cheap enough high quality green laser only for pointing, suggestions ?

    ^^^^^^^^ THIS^^^^^^^^ Paul we seem to constantly post about the 301's being a good starter laser and the best deal;) :unsure:There has to be a way for new members during registration to see something as a explanation as to why and how cheap they can be..:unsure:

    Looking for a cheap enough high quality green laser only for pointing, suggestions ?

    You can look into a 520nm direct diode laser build. They work in cold weather as the 532's DPSS don't like and work well when it's cold. Sanwu is good source but if you want quick shipping there's a couple great top notch member builders that can put one together based that live in the US. :)

    Looking for a cheap enough high quality green laser only for pointing, suggestions ?

    The radiation is called "IR" and is a bi product of how these DPSS laser's are made. It's relatively safe as the IR is kinda low and is focused straight out basicly with the beam of the laser. Your cheapest option is a 301, 303, basicly any 301, 302, 303, 304, which are really the same laser but...

    Some help for a newb with his parts list and its compatibility?

    I don't think those 9 volt battery's will work. They will most likely sag to nothing under load, plus GTL's aren't the best batterys and the 900mah rating is false.. Best to get 2 18650's and and they have the same case holders for them. The Black buck 8 is a big driver, are you sure it fits in...

    520nm 120mw green sanwu pocket laser lightly used.

    I don't see a Sanwu pocket 520 at 120mw. Was it metered because it might be a little better 150mw version that they have. Good luck with the sale:)

    Hello from Malaysia

    Welcome:) I'm glad you found a source closer to you to help build your projects.;) It has to be so hard seeing parts for sale and no way of getting them which is pretty common here. Stay safe!

    Green laser recommendation?

    Iv'e tried a 520 at 170mw to scare away seagulls from on top of a light pole that happens to be over my car that they constantly leave their droppings on. Ok they are not geese and are more a nuisance bird that prey on food scraps. I found the laser light doesn't even reach them before they fly...

    Best Burning laser

    Yes, iv'e been machining off and on for over 30 years. Brass is used only because it's the easiest to machine and fastest and easy on the tooling to cut costs, pretty much like butter compared to other metals. It's not good as a heatsink. Yes aluminum is surprisingly very abrasive and the...

    Best Burning laser

    Wow this thread is still goingo_O The only thing I see is they might of lowered "some" prices on a few certain laser's to get you through the door but the stupid claims are still there.. The 5000mw 405 you posted is classic:LOL...

    Best Burning laser

    Yes the ebay China ones can and will do close to 3W's. If you want to go that route why not try a Thor brand which you can get for less than $100. They have the "potential" to last.. You will come to regret buying from Laserpointerpro some point down the line when you see a similar laser for way...

    Best Burning laser

    Go to ebay and look up a 301, 303 405nm laser and you will find the EXACT same laser for around $5 as your 2nd Laserpointerpro link.. $10 with a cheap battery and charger. Maby 150mw tops. A 405nm laser is max 800mw for the best diode which I assure you this unit does not have.. Laserpointerpro...

    Full copper host 26650 x2

    A nicely pushed green 520 7475 at least on one of the hosts. That beast should keep it cool enough for some nice pointing time.:)

    Full copper host 26650 x2

    I clear coated 2 copper of my hosts from Rich with Krylon spray. Mine were only copper up front. One is a M140 at 2W and the other a 505 at 60mw. "I" can't really think a coating of way less than 1mm would make a difference?? Unless someone knows for real. Thats also one massive host?? Alaskan...
