JDSU 2214ML Test Run Photos

[FrothyChimp]

Here's the first coherent light from a JDSU 2214-40MLA argon laser I pulled from a PerkinElmer 377 96-Lane DNA sequencer.

Here is the power supply for the system. This is not the original power supply that came with the sequencer. This one runs natively on 110VAC:

If you want to run one of these bad boys you will need to jumper the control input or use a slick control interface. I recommend getting one of these as you can find them from time to time quite cheap.

Here the interface is attached to the power supply:

Hmm this doesn't seem to fit into the power outlets:

NOW it fits

Here's the laser and power supply all hooked up:

Now I really wanted some air flowing across the tube but the original cooling fan is 220VAC. I don't even know if the thing will startup on 110VAC. I'll check it though, later. I just hooked up a 6" household duct fan with a reducer to 4" and another reducer to 3". All duct taped together and wired we have a basic cooling system.

Now it's ready for a try:

Let there be light (at 488nm)!

Tube current at idle: 4.04A. No issues whatsoever with the tube igniting. Just a 30 second or so warm up, CLICK and pow, light.

That's a nice looking system.. I especially like that fan setup. I'm assuming it's single-line since I only see 488..

you have 808 posts BTW

the ML in the designation is multi line but at idle the only line resonating is the 488nm line. When I crank up the amperage it'll put out more lines.

In order to see the color lines you need to bounce the beam off of a diffraction grating.  Straight out of the laser it is only one "color."  Below you can see the original beam shining across the diffracted beam. It is probably producing all the color lines at idle (sometimes they need a bit more power for all the color lines), but they are "combined" right now.

Peace,

Thanks for the useful info as always Dave.. Aside from the 488nm in Frothy's description, I noticed that the dot was a bit more blue than the cyan that multi-lines usually put out..


Love that pic BTW..

Is the laser in the picture the one you took out of a DNA sequencer? Was it the same type of sequencer as frothy's? I can't remember.The laser head looks pretty similar though.

I just ran the beam through a prism and there are 5 lines oscillating at idle

Looking good frothy

I think I'd totally get an argon if I wasn't saving up for 635nm :-/

Yes.  Yes.  However, all of the 2214 series lasers look the same. One of these just sold for a whopping $9 in North Florida.

You've gotta hook me up with these deals - I could use some 488nm photons

I told the people that I know live in GA, FL, & AL.

Somebody got one helluva deal

Peace,

[MarioMaster]

aww

 

[GooeyGus]

Lookin' good there!

Start on the first click and 5 lines at idle seems like a pretty healthy tube

Any idea of hours on the tube? Does it have one of the built in hour meters that is attached to the plastic housing on the cathode end of the tube?

Didn't tell me!  :'(

Sorry. Didn't realize you were interested in the gassy side of things. Maybe I'll just post them all from now on. I watch several used equipment dealers & auction houses.

Peace,

I have the remote interface module too. That is a nice feature with push button control and metering.
