I apologize,

But I was curious about the post where there are three red laser beams
and that video with that pointer with 7 blue diodes ... in this regard I wonder,
How do you create such a laser pointer? well 3 or 7 module diodes connected as? and above all how to make them work together with the act of ignition?

Sanwu sells a tri-beam laser it uses one diode that has three emitters. Think it was Alaskan ( forgive me if I'm wrong ) that bought just the diode off them and built his own. It was real sweet. Posted some real nice beam shot from it.:drool: Sorry but don't know the video your talking about. Hope you find the info your looking for. :thinking:

I was only thinking of buying a tri-beam red, I have a host I think it would go nicely in, but haven't bought one yet.​

The G85 tri-beam is the one you want for CW out, the G84 is pulse. The G85 puts out full power at about, or just under 2.2 volts @ 3 amps. Probably a BlackBuck driver should work well that is rated up to 3 amps current.

G85 spec sheet:

Ebay:

1. BlackBuck driver rated at 500-3000 mA: https://www.ebay.com/itm/BlackBuck-...ver-for-M140-NDB7675-NDB7875-etc/152701561115

2. BlackBuck driver rated at 1000-6000 mA: https://www.ebay.com/itm/BlackBuck-6-6A-buck-laser-diode-driver-for-NUBM44-NDB7875-etc/162671640234 - I'd buy this driver instead, you will have some headroom and can use it for other higher power diodes later, if you want:
