It's only 10mm so if 2 cells that's just a 5mm solder button each. 22600 The 1st 2 digits are the width ( 22mm ), and last 3 digits are the length ( 60.0 mm ) OP could also make a conductive spacer from a slice of a wooded dowel or poly rod with a conductive core. Some people use neodymium...

Just use a 22500 in place of your 22600 and add a blob of solder to make a button if needed, remember to rub the blob against a piece of sandpaper on a flat surface to make a good flat contact patch.

Hey zigzag123, how are you? I know you can get small batch circuit boards custom made, I haven't looked at ordering any in a while, but if you search it out, you will find it. Remember to vary your search wording and keep plugging away, literally everything is out there. Here's just a couple...

Are you building a flashlight style laser, maybe you could use one of the round battery board drivers? https://mtnelectronics.com/index.php?route=common/home

In their pic you can see they are non button tops. Any quality 18650 cell should be fine for a 1w.

Almost 12W at 21C, very nice.

Yeah, still waiting. Have you seen anything for sale?

Yea I know, frightening.

Thin steel such as tin cans and razor blades yes, from up close, but these hand helds made from pump arrays lack the proper cooling for sustained work.

Spotted this XJ-F11X only 233hours 100.00 w/free ship.

Very nice Paulostool, I'm a big fan of multiple beams myself, here's a thread I made of my multiple beam musings with some pics, I also have some new ideas that I hope to find time to work on someday. https://laserpointerforums.com/threads/multiple-beams.106896/

Please post your results and some pics, we always enjoy seeing new builds.:)

You are responding to a post that's almost 8 years old, it's very unlikely that you will get an answer.

Use the words : Laser Igniter Lens to search for the nir ar coated quartz beam expanders and optics on offer from China, they are the best deal. Also, as I expect you know, those pumps output a knife edged beam bundle with each beam having uneven divergence.

I don't suppose there's any chance that anyone has seen any NUBC31 or NUBC32 diodes in the wild?

The last real post by JL prior to this was in 2021 and last real thread was 2013.

Attention LPF members, for those of you who are unaware, there is an ignore button, just click ( Aorus Forever ) then click ( ignore ) same as I did just now, and the troll's rantings will be no more.

Happy New Year and safe lasing BotoX.

Well..... the category is " other " and there's about diddily squat going on here..... just thought it might be of interest, also I suppose optical computers have a potential to be used in future land/building based AI to reduce the huge power demands, but that's yet to be determined...
