OK, so I've had a total of 3 of these unbranded lasers delivered now - 405nm, 488nm and 505nm. They look reasonably well finished, and the beams are good. However, only 1 of 3 is what I would call satisfactory wavelength: The 488nm is pretty good, at 492nm, that's fine by me. However, the 405nm...

As title suggests, has anyone got any experience with the generic unbranded "Sanwu-esque" stainless pocket pointers out of China? They look much the same, but are fixed focus. Very similar looking build, and take the same cell (10440). eg.: https://www.ebay.co.uk/itm/396058908511 Around £40 for...

Yes I'm considering getting a couple too. I was thinking definitely a 505, I love the look of that colour, and I'm sure it's even better in real life, as is the case most of the time with laser light, the camera rarely does it full justice.

What's the DD Sanwu pocket range like, worth the money? I like the look and form factor, not sure what beam specs/lens quality is like etc though?

About 10yr ago I had a couple of then very expensive CNI dpss, one of 473nm and one of 593.5nm. I sold them on, which I now regret, wish I'd kept them. The orange one in particular was a very nice shade. EDIT: I say then very expensive, but a quick look suggests they're now even more expensive...

You're right about beam specs, that's the main thing I like about them, nice tight beams. Though my 303 green is doing something strange, after its had a bit of a warm-up the beam starts changing about 1sec after firing, the beam dims and the spot gets a bit wider. From what I can find out this...

Ah I see. So the ktp is made for the job then. I'm guessing that the fact I haven't seen a 404 dpss means there isn't a suitable material in existence then?

OK so be gentle, as although I've been dabbling in lasers for some time now I'm still learning the ins and outs of optics and the complex processes that go on right from the diode, to optics and solid state pumping and the likes. My question is this - I understand that a common 532nm green DPSS...

Oh dear, what happened ? Laser burn ?

I will get into building at some point, I just wanted a ready made for the collection. I did make a red burner once from a dvd-r drive, I pulled a pen pointer apart and mounted the diode in place of the old one and altered the driver to suit. Long time ago now though. I'd love to make a 1W...

Tbh it could well have come from China originally, like GSS says it's so identical it's probably rebadged from the same mass produced generic unit. Anyhow Zeus' customers who've fed back all appear to be happy, and the chap takes time out at late hours to communicate, it's the little things I...

OK, will do. The uk on my u/n denotes this also. We are both talking about Zeus lasers, right? They are based in Greece, and that's where their warehouse is.

Not really, I am in UK which is only 2hrs behind Greece currently.

Order placed! Just have to wait for arrival now. They had to send from an alternative warehouse but as a result I've had a free upgrade to UPS urgent package. Great customer service, the chap was immediately replying messages in the late hours of Sunday night!

Is it worth another $50 for a beam expander for it in your opinion? Does it make enough of a difference?
