Finally received this crazy handheld laser from sanwu about a week ago and I am very impressed. Obviously it's crazy bright and burns like a champ. The host quality is much better than expected and I was expecting border line perfection. The host is MASSIVE and built very well. Very visible beam in the daylight.




Divergence is terrible as expected, but what I didn't expect is a 2nd beam that shoots parallel with the main beam. It's very visible and hopefully that's clear in the picture.



Overall I'm impressed with this laser. The 2nd beam that's projected along with the main beam really kills it for me. It ruins the look of the laser output in my opinion. This would be an easy 10/10 review from me but personally I can't stand that second beam. I'll end it off with some shots, including a size comparison with some other lasers.

Awesome looking laser PolarAZ, its a shame you have the double beam problem, maybe there is a fix for that, have you tried contacting Sanwu about it?
I would expect a powerful Sanwu laser to have bad divergence and light artifacts, that's a thing to think about before buying one.

I cannot quite see a second beam in the photo, I see extra light next to the main beam which looks like what I call wings. Can you find someone else who has one and see if that is what happens with all of them, or just yours? Sanwu should be the go to for that though.

Thanks for the review. What lens are you using? What does the raw output of the diode look like?

E-mail Podo/Sanwu and tell it has a second beam which ruins it for you not to mention makes it defective----no way a first quality example should has a second beam.

They should repair or replace it for you.

No reason for you to just accept that---is unacceptable.

Yep, especially for such a high price.

Thanks for sharing, Polar, I think I see your second beam in the second photo, it looks like you can see the dot below the main beam, and can just make out the beam.

As Encap previously mentioned, I'd contact Podo/Sanwu, this isn't normal.

I'm going to ask something very stupid on my part..Are you referring maby to the wide axis of this multi mode diode as the 2nd beam?
Turning the host in hand 1/4 turn will make it show brighter or a little dimmer..

That's not what I'm referring to. I opted for the g7 lense to clear that up for you guys.

I guess I still don't get it. Regardless of the lens used you shouldn't have a satellite beam in addition to the main one. Couldn't see what you are talking about from your photos. I hope you are able to resolve any problems you are having as Sanwu doesn't exactly give these lasers away. Good luck.

May have found the issue. There's hazing in the shape of the beam on the lense.

I would contact Podo here and tell him your problems. This is a brand new laser and shouldn't have any lens problems. I would think they would fix this for you.

The dust cover reflects part of the laser beam sometime, you can adjust it(nose tweezers, turn it counter-clockwise) to remove the blemish.
