The earliest green laser pointer that I know of anyone buying was in 1991, pretty sure it was a billionaire too. A relative spent $4100 for a 1.3mw handheld green in 1994, so that's probably pretty close to how much they cost when they *first* came out. Anyone remember how expensive 405nm...

Sorry for the slow reply. It's always funny when that happens, but people (at least in my experience) are beginning to change attitudes about laser pointers. High altitude lasers are the best. Get a 1W 638 with a beam expander and the dot can be seen (with binoculars) 30+ km away. I'm sure high...

Looks like ~60mw to me, but reasonably bright for a yellow-orange pen laser for sure. If you're having second guesses about selling it, I strongly recommend you keep it. There's likely a good reason for keeping it that you're forgetting about, or at the least, you on some level feel as though...

Fair enough. I guess we'll just have to wait and see.

I honestly wouldn't mind being from the outback boonies as opposed to Calgary. Shining lasers these days catches a lot of attention, especially the bright ones so It's irritating to only be able to use them outdoors occasionally. I've got some good photos kicking around, I'll post them soon...

I'm in Calgary. You?

Not much, yourself?

I'm siding with LSRFAQ on this one. One could easily avoid >95% of the organic extraneous material that would contaminate the fiber, by using a ~50 micron buffer, which if you look closely at the razor in the video, it is there. Further, the smell wouldn't be present if: the actual site of...

Peak and stable power on the 593.5? Might be interested.

I'm quite confident the price would be significantly lower for even a small order of 3 or 5. You should inquire on pricing for 3, 5, 10, 25. Or something along those lines, because I can easily see quite a few people ending up wanting these if they could be had for under a hundred bucks...

Re: Need car sale. 520nm 532nm 660nm 594nm LPM Hey, I might be interested in both the red and green 520nm laser, albeit I am in Canada. Also would like to know the hour usage on both, approximately, and the divergence on the red as well as output beam diameter. Thanks!

Does it produce any heat when its powered up?

Re: FS: 1.2W+ 520nm new price Hey, I was wondering how you felt about shipping this to Canada? Wouldn't want to buy a nice laser like this and have it snapped up by customs. Also wondering about duty cycle, lens, and battery. Thanks, AAlasers

Tungsten is a relatively expensive metal to buy in raw form (10-30$/kg), a moderately expensive metal to buy in a basic machined form (rod or sphere) (60-200$/kg), and a very very expensive metal to buy in a complex machined form (laser host) @ probably around 1500$/kg. A simplified host would...

There hasn't really been much of a reason for this particular kind of divergence mitigation in a diode, but here is a theoretical method that mimics crystal-based modules: Condensing and subsequent optical correction of beam. Say, have a lens with a focal length of 0.5mm that's the same size as...

Well, that's a bit of a disappointment. I suppose the post still stands for the purpose of a possible driver for this diode. Additionally, there are creative ways to mitigate non-parallel emittance, but the easiest would probably be an AR coated FAC lens. I think people should be looking into...

Hello all, Haven't posted here in a while, so I thought i'd start it off with a diode I just found on the semi-reliable O-like. Mitsubishi 638nm 2.5W red laser diode/double laser beam [OL-M-2.5W] - $129.00 : Zen Cart!, The Art of E-commerce 2.5W @ 2.8A & 2.4V doesn't sound too bad to me...

Hello, It is my understanding that over the past few years, the importation of lasers above 5mw into Canada has been prohibited. Is this in fact the case? I wish to purchase a PGL-III-C-589 (>80mw) directly from CNI, soon. Would I have to worry about it being seized? It's quite an expensive...

Yup they're probably real. I'll be willing to bet they'll be under-spec, and will probably last a while if you keep the duty cycle reasonable (<30sec on, 30 sec off). However, they use AAA batteries, which is a pain to keep using. They get quite expensive. IMO, expect low quality and $h1t...

Hello all, I was wondering if anyone has tried combining these two wavelengths before, and if so, to what degree of success. It might seem a little bit pointless given the relatively similar wavelength, but I believe this combination (with a single-mode 445nm, and high-power 405nm), could...
