Just a 635nm Striker/Saber beamshot

So, I received my lovely 1 watt Sanwu 635nm(bright red) Striker/Saber today! Really nice jewel of a red laser. This one has the magnetic dimmer switch and magnetic mode ring. This is my first actual red handheld laser beyond just the ole' cat pointer that still actually works.

The power is adjustable by a ring that you twist clockwise to increase power from 0 (full counter clockwise) to Full(full clockwise) . In these pics, I discovered later that I didn't have the knob all the way to Full.. So this is about 3/4 power
I have the 3x beam expander on it by necessity as this is really the only way to tame this crazy beam! I don't know exactly which diode it has in it but, it's definitely a big multimode. But I was expecting it to be nasty laser but it's not as bad as I thought it would be. Actually it really is kinda cool like it is. Just a raw, nasty little laser. It does round off my collection with a nice Dark Side vibe. Like something an evil alien would shoot at you.

My camera really isn't picking up the beam much at this wavelength for whatever reason, but the beam is much more visible, richer, and dare I say, 'bloodier' in person. Like shooting blood across the yard, lol! Anyway, now that I've discovered the seven neat tritium vile slots on it for use as dial indicators and on tail cap, I'll be ordering some of those. That'll really make it look nice in the dark.
Overall, a great well made jewel of a laser. Thanks Sanwu!

Yeah, these have horrible divergence specs. Your third photo looks like it has two beams. Is that right? It shouldn't at just 1 watt. I have one I built years ago that does 1.1 watt and put it into a Cyprus II copper host. Yours does look dim in the dark which doesn't seem right at all. Well, enjoy.

Yeah, I see that double beam in the photo now after the fact. But no, it wasn't like that when I shot it. I think it's just at that exact instance, the spot was moving across two reflective spots at the same time right around there. With that beam expander, the beam really tightens up at distance. It's sloppy up close though even with the expander.

Yeah, it looks dim in the picture, but it's much brighter in person. my camera didn't pick up the beam much. Plus lower power setting by accident. I'll see if I can stick another pic down below at full 1watt

That BE is a good choice with this laser. If you want something other than a line at distance, you pretty much have to have a BE or use Cyl lenses to try to tame its divergence. I have a project on the back burner to Cyl lens correct a Mits ML501P73 at 1.2 amps.

I'm guessing the ML501P73 is what's used in this Striker laser also? .. I wonder why this larger host is described as 635nm @1W, while they have another model red one that's just a little smaller but *638nm* @1W.. Why the 3nm difference unless they are different diodes? Heat levels maybe?

It would seem that about three or four years ago they started calling these 638nm laser diodes instead of the 635nm that used to predominate. Why they did this, I haven't a clue, but it is the same diode. The difference is likely because of this disparity in WLs.
