First I want to say I'm really sorry for this necro post, but this thread was very informative about the relation between law and police discretion and stuff. I really think everyone here should read this thread. Second and finally: This guy made my blood boil. Anyone who thinks this way get...

Yeah thanks to Paul and Alaskan too, kecked typed out an essay tho. 🤣

Great read keck thanks for putting all that into perspective. Pretty sure the expansion lens is gone forever so it's an 808nm laser unless I can either find the lens or successfully remove the KTP for a 1064nm laser... but I'd imagine that would need the expansion lens too.

So I have/had a junk 301 532nm laser. It was mode hopping like a boss. I lost the expansion lens getting the crystal set off. Now I have a decently focused 808nm laser. My question is: should an 808nm laser burn better than it did when it was a 532? Because this one doesn't, it seems a bit...

I just got that 405nm laser from sanwu. Unfortunately it's defective and super dim. I sent an email with pictures to them and they're sending me another one! So yeah it's more expensive but they back up their product. The 301-304 lasers are sometimes complete junk, so buy a few so you'll get 1...

I have 2 sets of safety goggles that block 808nm. Are you telling me viewing the beam (not the dot) without goggles is going to damage my eyes? Because I kind of doubt that. I don't see a faint red glow I see a vibrant yet deep red line, the beam itself. So anyway what's a good solvent for that...

Yep thanks. Honestly half the fun is cracking them open and see what makes them tick tho. In fact with this mode shifter I just now tried prying the module out, slipped and the expansion lens or whatever it is separated from the crystal set and went flying! Maybe one day I'll find it LOL...

:/ well thanks. Not gonna toss it, gonna use it as a guinea pig I guess.

Are you trying to say that the temperature makes the crystals alignment change?

I have a mode hopping 532nm 301 laser. Pretty sure it was like that the moment I received it, only have had it about a week. So when I fire it, it starts at TEM00, and within a second the beam splits and rotates to at least TEM01 or TEM10 whatever, 2 dots. Every time. So i decided to do some...

So ive spoken to francis and looks like hes taking care of me. :D sanwu website says 1x18650 or 1x 18340. 3.7v. Putting 7.4v in was just a thought. Will definitely try a pot mod when the replacement gets here. Edit: no the driver isnt accessible without pressing the module out i guess. Ill...

Ah thanks for reminding me atlas. So all of my 301s have 1x 18650 battery in them and ive tried swapping the batteries around, doesnt make a difference. BUT i did stumble upon this: and wanted to know what happens if i stick 2 16340s in there instead? Im assuming the driver will just keep the...

Does this look like 100mw of 405? Dot is on white popcorn ceiling. I've contacted sanwu, we'll see what they say. Hope they're as good as everyone here says.

Thanks for the responses. So considering it can't burn anything would you say a desperation pot mod is in order? Remember all my other 301s have no problem burning things.... The problem isn't me. Also if you compare those 2 pictures^^ i would call that exceptionally dim. Edit update: sanwu has...

My camera actually picks up the beam (sometimes?) and the dot looks much brighter. Here's the 100mw 405 vs the 200mw 650 Also the pic in the other thread, the light is being flourescente'd so it looks brighter and bluer.

Yes. I can get a very very small dot at ~3 inches. All my 301s make electrical tape smoke when i do that, except this 405. I put up a thread in the violet laser section with a picture. Pretty sure the laser is beat.

I posted in the sanwu company thread already with a couple questions about this issue I'm having, I have a picture now to better describe the problem. Is this a beat laser? This is with focus cap/focus barrel whatever removed. Looks like diode is shot. I did put the battery in backwards as soon...

Hi i just bought 3 sanwu 304 lasers, a 405nm 100mw, a 532nm 80mw, and a 650nm 200mw. I have a couple of questions. First I'd like to say they came all bubble wrapped and were here in a timely fashion. Awesome. The 650 and 532 are super bright and burn things instantly when focused! The 405...

Hey I have a diode in my gatling chinese guy that isn't listed here. (or I'm dumb) On the can there is a "sb479bj91" which looks like a sharp diode, and i see some sharp diodes have 2 part #s ("sb###" and "gh###"). I do believe mine is a multi mode... Would correlate to the one 450nm sharp diode...

Encap: survival lasers doesn't seem to have a host that accepts 2x 26650s.... The s4x looks like it does but in the description it says 2x 18650. Lifetime: I am fairly interested in that 1w 520! What's nice is you live somewhat near me (saw you on lpm map) but that's not what I'm really after...
