Rare Wavelength from Cytometry Machine!! All wavelength added!!!!!

No hene needs cooling, and that's the only gas wavelength that would be in it.

488nm would be gas unless the OP claimed the 488 was solid state somewhere? That said, he did't mention anything that sounded like an argon, just two glass cylinders which would be HeNe.

just comment what do you want to see and i'll upload it.

Proof that everything you have said isn't BS? Like, i dunno, the actual machine?

Sorry for double posting but the 380;445;473;488;503;532;638 is direct diode... But 540 is dpss;780;594;612 is Gas.
All the diodes are single mode. And tried to take the picture but iPhone won't pickup the beam...any advice? The diode extracted came with it's own driver but I need someone to lpm it and how to upload photos here using a mobile phone?

Hmm... Maybe he meant DPSS?

There are 488nm diodes, but I don't think those would be used in a system like this. I am also very skeptic about this...

There are 488 diodes for about $4k

Yea, I'm still calling bs on this- that's probably 25,000$ worth of diodes in there alone, 2 very expensive solid state units (which BTW, "540" doesn't exist, it would have to be 543nm), and a very expensive HeNe which as far as I know hasn't been in production for quite a while...
All evidence says this, ladies and gents, is a load of poo. I'd be fine if I was wrong, but I'm pretty sure I'm not

There are pretty high powered 1080nm laser diodes available, so if the DPSS is actually DDD (direct diode doubling), then it would be true. Not believing this either, but you never know..

I can say never once have I searched for a part number or manufacturer number (IE the IBM6601571) and not had anything come up at all. In this instance the only thing google returned is THIS forum post. Not saying this is BS, just that the part number provided doesn't provide any search results in Google. So I am saying Google hasn't heard of it before. Google knows everything.

I did this for all of the photos he posted.

They all say the same thing. I know it's not necessarily conclusive but. Still.

I believe 612nm can also be obtained from a very, very complicated DPSS process!

I've seen DPSS get to the 604nm-607nm range, but I can't say I've ever heard of 612nm DPSS. Even if it did exist, it probably wouldn't meet the power requirements for flow cytometry. And a 612nm HeNe would still be a lot cheaper.

Of course! I just brought this up since I had a discussion with ultimatekaiser over Skype & we talked about it briefly. For the amount of money it would cost to make 612 DPSS could you probably buy a few 612 HeNe's

Alright yeah my benefit of the doubt officially ran out.

I call bullshit.

1) Anybody can do a simple color swap. GIMP software, 1.5 seconds of work.


2) How inhumanly difficult can it be to post a picture of the damned machine in question?

3) My original question STILL went unanswered - how did you know how to driver the diode, at what current and voltage?

Until we can resolve #2 and #3 here, I'm claiming #1 as entire thing this thread is about.

^I knew yellow diodes existed somewhere

Man, I'm having a hard time time with this. Everything so far points to this being fake, but I so desperately want it to be real that my mind won't accept it. :undecided:

I haven't been here as long as most of you, so I still have some patience left. I'm giving it 'till Wednesday before I give up.

There, on a whim I went to reproduce the exact color of his alleged "503nm" diode.

It's the easiest to do with Green color, only need to nudge the green hue a bit without changing the rest of the picture much. My best at color reproduction:

IF IT'S NOT CLEAR, THESE ARE FAKE, I MADE THEM BY HUE-SHIFTING IMAGES OF 400mW 532nm GREEN LASER!




Further analysis of his new pictures in the opening post with "more wavelengths":

1) 503nm, 473nm and 532nm "diode" lasers all appear to share the exact same host, likes of which I've seen in cheap green lasers.

2) The copper module + heatsink shown in the photo does not belong in such a host. I actually sell a heatsink for these types of hosts, called "Classic" in my shop. It's a two part heatsink because the space is at brutal premium in that host, there is NO way it would fit a heatsink that wide.

3) Pictures in his post in this order:
#9 (Red laser, beam straight, no host visible)
#5 (Green laser, host visible)
#4 (473nm alike blue laser, beam straight, host visible)
Are taken at these dates in this order, according to metadata which he didn't bother to erase before uploading to photobucket:
16th, 20:12
16th, 20:13
16th, 20:14

My opinion: Same laser, different angles, photoshop work. Photoshop Elements 9.0 for Windows software, to be precise.


If I were building some lasers like these, I would take pictures of them during construction and photograph each after it's completed, instead of completing all and taking pictures of all of them afterwards. I'd also photograph the shit out of the machine these diodes came out of. Just me, though

Again, how does he know how to drive these diodes? How do you look up a datasheet if you don't know the exact intended output power of the diode? Simply searching by wavelength can't really cut it.

EDIT:
Something else:
4) His picture of the unmatching module+heatsink combo does not have "Photoshop Elements" in metadata, which means it's not changed. He had no reason to. HOWEVER, it still has the resolution of 3264x1840, which is some 6 MP resolution if I'm not mistaken - the exact same resolution all of his other photos have, and yet they all have the Photoshop stamp in data.

What did he change, if not resolution?

Seems 612nm is still being sold by Meredith Instruments(HeNe):

I'll keep looking!
