As the current increases so will the voltage requirements. If you have it locked at 2.2V then you won't be able to go any higher with the current. Try setting the voltage to 2.5V and slowly increasing the current from 0V. You may need to go even higher than 2.5V to get the full output but that's...

You should move closer so I can beat you into making hosts too!

I can only beat them so much though!

I need a machine operator and an office assistant!

Yes, that would be awesome! I have a CNC lathe, manual lathe and manual milling machine. I would love to put this CNC lathe to work.

I have all the equipment to do it but I just don't have the time to do it all myself.

It depends on the diode but most of the higher power multi-mode diodes have pretty terrible divergence. A beam expander will help quite a bit though depending on exactly how far you're trying to point.

Welcome!!!

Welcome to LPF! I've got a lot of current items available and I'm here to help as well.

It mostly has to do with new shipping regulations. Lithium batteries aren't allowed to be sold separately in marketplaces like Amazon and Ebay anymore unless they come pre-installed in the equipment.

I have plenty in my ebay store. Let me know if you have any questions.

I still have a few of these.... never even tried to hook them up.

I ship worldwide.

It's great to have you back!!!!!!!

I've got a few buck drivers that will work.

That could be a whole new market to explore!

I just went to AliExpress and this is what popped up.... WOW I can get laser diodes, drivers and baby parts. What a time to be alive!

I think this or a less powerful version might be the pump diode: https://www.ebay.com/itm/254310199749 The module certainly looks like it has a C-Mount diode inside.

Didn't really get much interest in it. If the minimum order quantity comes down I'll grab some but I don't need 49 of them.

I was able to capture some photos through a welding mask and playing around with the camera settings. It lasted for quite a bit longer than I remember other ones lasting for. My eyes don't seem to hurt at all but I'm probably immune from staring at laser beams every day. LOL.
