I ordered that 638nm single mode from lazerer and when i got it, it worked for 2 minutes and it kept shutting down for no reason. Tried with many full charged batteries, not working. Now it doesn't turn on at all. Same happened with my xpl 532nm. Worked fine for a month and then suddenly shut...

What? Is the 300mw 638nm single mode diode? I thought it was multimode. What diode is it?

My 800mw 520nm 1.5 mrad with 3 element.

Re: Various lasers 4 sale I think i'll take the altoids laser. So it can use 2 10440 3.7v?

Nice. Imagine... with g2 lens it would be like 7 mrad lol. G2 sucks. 3 element ftw

Re: Hyperion Laser Power Meter For Sale: 2W & 6W Version Me want LPM.

Can u measure it?

Divergence?

Imo it's going to be ALOT brighter than 500mw 532nm. People still trust the "Relative Perceived Brightness Calculator" ? It's not even correct. It claims my 140mw 520nm dot is 1.8x brighter than my 1300mw 445nm dot. I checked and the 520nm is not even brighter lol. The 445nm is little brighter...

Yea im sure. It sees my other green's IR

I have with a camera, not even IR is coming out. Yea i told him, waiting him to answer.

Ok this is weird.. when i press the button for 1 min the host still gets warm like the laser is on but no laser light is coming out...

Lo the thread's title changed to " mystery" company xD Btw my XPL 301 150mw 532nm stopped working... i don't know why. I don't think the diode is dead because sometimes it gets on for a split second. It's not the battery either, i tested with many different full charged batteries. What could be...

3 element. It's best. I use it in my every laser :)

No i don't. In all my calcucations 3 element gives 0.25 lower divergence than g7. I'd guess with g7 u would get like 300-500mw more power than 3 element with that laser.

I'd take the 3 ele cause i like lowest divergence. Like my single mode 520nm 60mw is 0.25 mrad with 3 ele, 0.5 mrad with g7, Which one would u choose? hehe. The g7 gives so little more power it doesn't really make difference in brightness.

3 ele still gives the best divergence. Just measured my 520nm 800mw divegence: 1.75 mrad with g7, 1.5 mrad with 3 ele. 3 ele ftw.

If u want lowest divergence get that 120mw 520nm. It's probably like 0.5mrad. And those 532nm are really like <1.5 mrad

I bet it's 9mm diode. The divergence is so bad it can't be anything else. PLP520-B1 has divergence like single mode.
