Does anyone besides Laserglow make high power handheld 635nm units? Unless they are using C-mount, there is no excuse for the poor focus. I'd actually love 1W 635 in a compact package, untilzing LiIon. Anyone up to building one for me? or a 500 mW?

Well to me, the beam IS blue. It is a certain sort of deep, techni-color blue. Very beautiful. There is very little violet in there. The only reason you can see the violet is it shows better at higher powers in ambient atmospheric dust. Put your 445nm in a little smoke or fox, and all you...

Why is it that conversion efficiency (potential) seems to be inversely related to pump amplitude? I keep hearing of insanely efficient 532nm DPSS squeezing even 50% input towards doubling. I hear of little microcystal tricks. Is a highly efficient xtal easier to grow for a relatively small...

Is there anyone who makes 1000mW 532nm in a nice host at a decent, reasonable price? Also looking for a 500mW hand-held 63*nm with good focusing abilities.

Most people know what you really mean when one speaks of UFO/OVNI. We are referring to ET most probably, or possibly a large living organism which lives in our atmosphere, and possibly in another dimension. There may be little distinction between many of these, and the god/Jesus concept...

I believe Laserglow has perfected the 589 technology through their own in house tweaking of the CNI's they sell. The Rigels that Laserglow sells are uber reliable. I have had mine for a few months now, and not once has my Rigel failed to lase. I have to say, even though the 593 is brighter, I...

Melatonin behaves similarly, and is one way you can test for it's presence. The half life of the electron fall back is very short ~.2 seconds, but you can notice it. I wonder weather it might be possible to use 405nm as a pump, and shoot through some artificial crystal to come up with a new...

I don't have an AZIX module, but would so love to have one of these. Can you work with me on this. Just tell me what you need from me. I like the updated lens solution. At these powers, my GOD. And shape, let alone composites. Best, Alex

Can you point me to link on new price on golden pointer please? Thanks.

Does anyone here with a decent reputation offer the 445-450nM blue laser diode pointers at an affordable price? Would love to have one, and can pay up front. Thanks.

Looks like they lowered the price to about $50 something, and free shipping. There are SUPER RARE (world's 1st ever solid state pointer). Once someone buys it now, it's gone ;) Thanks (yeh I'm getting a huge kickback from seller to say nice shameless things about this pointer...NOT!)...

wow looks like they unloaded a couple much cheaper. Someone must have told them the historical importance of this. The box it shows looks a bit different than the box my Sharper Image one came in (which looks like modified VHS cassette box/book), and fits nicely in bookshelf.

Already own this, but here is what looks to be new, old stock, and is the 1st commercially available solid state laser pointer ever made. Made in Adelaide AU, it came right after the world's 1st laser pointer (by same company, Laserex), the miniaturized LLP-100 HeNe. Looks to be in great...

Does this have anything to do with why you (apparently), arbitrarily blocked me from bidding on your items? If anything, creating enemies out of perfectly otherwise nice people (like myself) can only hurt you down the road. You know almost NOTHING about me, but now I doubt I will forget about...

Hey I actually saw a green diode pointer (prototype) at 3M about 10 years ago. The wavelength made the dot more dirty yellowish than a 532nm DPSS, and the avg. life was I think 50-70 hours? It was <1mW. What a unique thing to see. These were all PhD's I was working with over in their research...

Techlasers SUX! They tried to rip me off, tooks weeks to fulfill half an order, and the half of the order they did ship, was defective. It was a massive waste of time doing business with such a POS companny. Oh BTW, don't believe all the trying to sound Western type pseudonyms you are given...

I imagine it may be possible to make almost any wavelength laser through a nested DPSS process. Elegant, cost effective, and feasible? Probably not.

Amongst my collection are two Lyte Optronics units (one 637nm 4.*mW), and the other emmiting at 653nm and also 4+mW. Both opperate on AAAA. The color difference is barely perceptible to me. The biggest diference I notice is in the apparent brightness of the two beams. Within this range, as you...

sure you could!  but the color balance would radicaly change when you hit something which fluoresence a lot.  i often manually combine 405 & 532 at the appropriate amp each to get a rough idea, and you get this whitish sort of green which almost reminds me of day glo green, but whiter.  its a...

right, ramen spectroscopy and the like won't exactely enable huge mass production, and the big price fall we need for these to be used in pointers. but is it true, I hear the blue diode technology can be adapted to lase at many wavelengths, including red, orange, and even green. imagine a...
