    Argon Ion and Helium Neon Beamshots!

    Tomorrow I'll try and get a pic of the projected spot - it was about 18" diameter, a bit white-green, but pretty close I'd say. Glad you like!

    Argon Ion and Helium Neon Beamshots!

    I setup a whitelight projector this evening and here are some pics of the setup.. Argon was running around 30mw and HeNe around 18mw. White-light-setup--1 by Christopher Purdy, on Flickr White-light-setup--2 by Christopher Purdy, on Flickr White-light-setup--3 by Christopher Purdy, on...

    Just ran across this sweet piece of optical glass...

    Your last pic made me cringe... never lay a FS mirror down like that... Sorry to be "that guy"... It looks as if its a bit dirty... The coatings are super sensitive... if you decide to clean it, read up on cleaning telescope optics... no dry direct contact, no "lens cleaners", etc...

    What order do the lines in an Ar-Ion appear as you increase current?

    So based on this graph from spectra physics... The order would be: 514.5 488 476 496 458 529 In that order, correct? So for mine - the 529 isn't showing up then since I have 5 lines... Correct me if I'm wrong.. Please!!

    What order do the lines in an Ar-Ion appear as you increase current?

    Just curious - as you up the power and more lines appear, what order do they appear in? For example, mine is showing 5 lines, but I have no idea which they are... And what would be next if I could tweak it enough to get the sixth?

    Need expert input on Argon alignment

    I think I've got something taht will work for now. I took a velcro cable tie and wrapped it around the metal output tube and then ran the cable through one of the access holes. Now, as it runs I can gently pull on the cable tie and adjust the alignment to get more output. I then attached...

    Need expert input on Argon alignment

    Unfortunately they aren't external.. Its A JDSU 2214 series head. After a few more hours research into Sams FAQ I read that I can add a locking collar to the cathode end and use the setscrews to tweak... I'm planning something like this. I spent about 4 hours tweaking it and got a weak beam...

    Need expert input on Argon alignment

    Sorry for a new thread but I'm in desperate need atm.. So, my argon is all set, and I can get barely any output.. so after reading and reading and more reading I determined that the tube is a bit out of alignment. I put a long rod on the rear output side of the tube, and with extremely gentle...

    Hit in eye with 1000mw 445nm blue laser

    Just shared on my Facebook timeline... Hey guys - if we all like his page he will get a lot more hits and hopefully more support for the treatment! Best of luck my friend!

    Holy cats.... I just snagged a multiline argon for $100...

    Thanks for the response! In my digging I found *the* manual... with complete details on all modes and wiring from the OEM... http://www.junktronix.com/ebay/proddocs/JDSU%202010%20Operation%20Manual.pdf This breaks it down so even mechanical engineers like myself can understand the wiring.. :)...

    New setup for my HeNe, pics and Beamshots :)

    Very Nice! Something about a good old HeNe beam makes me happy..

    Holy cats.... I just snagged a multiline argon for $100...

    Thats interesting - reading the online doc's for the laser module it does appear that it self adjusts to maintain 3mw output... so maybe I wont need the remote for testing!

    Holy cats.... I just snagged a multiline argon for $100...

    looks like mariomaster had a similar one.. http://laserpointerforums.com/f43/beckman-uniphase-2212-argon-ion-59943.html Can someone drop me the schematic for the diy remote plug? I've looked and see several people have made, but I want the easy one with the single 5k pot and some jumpers...

    18mw HeNe is here!

    Thanks.... It was listed as 632.8nm but I have no way of measuring actual.

    18mw HeNe is here!

    Wow - 18mw of HeNe is BRIGHT! Theis tube is pretty much brand new. Not a mark on it or the PSU. ...and now, what I know you really want are - BEAMSHOTS! Running an interferometer setup: hene-2 by Christopher Purdy, on Flickr And just some multiple bounces between mirrors.. hene-1 by...

    Very informative video on a home build ruby laser.

    I found this over at hackaday.. The author goes pretty deeply into the methodology of getting a ruby rod to lase and what is required. He also goes into the construction of a power supply for the flash-lamp and types of flash-lamps. Its not up and running yet, but is a great explanation on...

    My optical table and breadboard build..

    Done... Its amazing how much the proper tools help. Untitled by Christopher Purdy, on Flickr Untitled by Christopher Purdy, on Flickr I had planned on anodizing or painting it black, but the brushed aluminum looks quite nice.. Another hearty THANK YOU to everyone, especially Bowtieguy...

    My optical table and breadboard build..

    A big thanks to Bowtieguy! He's local to me and we met up for a bit this afternoon and he set me up to get this project done right! Thanks again!
