Well, it was really fun, and I have some good memories, but I just don't use these things anymore. I'm not particularly active here either, so I'm selling my collection, hopefully with some reasonable prices. First up: 638nm HL63193MG @1.2A, S1 lens, 501B, 860mW SOLD This one is a blue 501B...

Huh. Well, that makes sense given this thing is nearly 20 years old. Still need to sell it though XD

Yeah, with the controller I have I think it does 10A tube current, and at that current it outputs 30-35mw. That's way to high for normal use though. Spec sheet lists max current at 8A, so 10 is going to burn it out real quick.

Hey everyone, I'm sorry that It's been so long since I've been on here. I've sort of lost interest in lasers for now, and I might start selling more of my lasers, but for now the only one I really want to just get rid of is my argon laser. I don't run it often enough so I want someone who can...

I'm just curious if those cheap ebay dichros would work with ~488nm and 638nm lasers so you could make a cheap white laser with them. Im not really planning anything yere yet, sotheres no real directon to this thread it's more just building the knowledge base for future reference. I think I will...

Anyone test if transmit/reflect blue+green reflect/transmit red will transmit/reflect cyan wavelengths efficiently? Hopefully you guys know what I mean. I actually don't know If there are reflect blue+green dichros.

Well, if the purpose is to make a laser that looks white, and has a white beam, I think that cyan+red would make for a very cheap alternative. Much less than $400, and also less complicated (in the case that you are not buying a prebuilt module). Interesting! how does the beam look? Id imagine...

Yes 638 indeed, I typed that way to quickly :crackup:. Vomit green and cyan would be an interesting combination but probably not white. Im suprised to hear that yellow and cyan would make white. It should be greenish shouldnt it? Cool! This is pretty much exactly what i wanted to see. A white...

I understand that blue and yellow LED's mix together to make white, so does it stand to reason that a cyan wavelength and red wavelength combine to make white? I could see pass blue+green reflect red dichroic mirrors being used along with red and the newer cyan diodes to make relatively simple...

Had an insanely busy day today, getting ready for college so had to get a bunch of stuff done, I will try to get those pics tommorow! Also, yes, knowing how to post pics to the forum would be nice, as I see things have changed since I was last on. EDIT: sorry, another busy day getting ready for...

Since everyone asked, I will get some pics up tommorow :)

Re: Argon Rated for 20mW Only Outputting 5mW Lol, I would but I already uploaded a few pics to the thread where I bought it. Im not sure if they are still there though.

Re: Argon Rated for 20mW Only Outputting 5mW So after cyp figured out the problem he told me what to do. A wire had broken off of where it was soldered, and after soldering it back, the laser is operating as expected! now it has a very clearly visible beam at 20mW. If i push the tube current to...

Re: Argon Rated for 20mW Only Outputting 5mW Was going to PM you earlier today but forgot, sorry about that. So I cant get a multimeter right now but I definitely will soon since there are many times I would have needed one. Something I cant beleive I forgot to mention in the OP is that the...

Re: Argon Rated for 20mW Only Outputting 5mW I dont even have a multimeter to check the voltage. When I say im bad with electrical stuff I really mean it. I understand the pinout, and the voltage across the pins that controll it and all that, but i really dont have the experience to risk...

Hey guys, so I just fired up my argon for the first time since I got my LPM and decided to take a reading, and to my surpise the laser (a JDSU 2214-20SLMD) is only outputting 5mW according to my LPM, even though its rated for 20mW according to the model number. It fired up on the first ignition...

We have the technology to do all sorts of crazy stuff nowadays, but it seems like people dont want to spend the money to do those amazing things anymore. PS: its sad that i had to log into my account on LPF again... i really should be on here more.

Yeah, id say that with spiders and centipedes, they certaintly do bother me with just their appearance, but the centipede is worse. And its faster, plus it bites (i think... pretty sure they bite not sting). The speed of centipedes does bother me more than anything though. In fact, i think a...

People also say that they hate milipedes, but they dont bother me at all.

The garage must always be just that much closer to hell, it lets the bigger ones come through XD ALSO, EDIT: glad to see all you guys, and sorry that my time on here has been spotty recently. I guess im just kinda between hobbies now, and lasers might be it but im not sure, i still like knives...
