Cheapest way to get some rare wavelengths?

Gonna jack this thread for a sec, sorry.

So will a JDSU 2214 head work with a 2211 PSU? Because there are tons of 2214 heads on eBay but all the 2214 PSUs I can find require 230VAC, where the 2211s only require 110VAC, but it's difficult to find 2211 ML heads.

I have been reluctant to buy 2214 heads because I, like thestug, only have access to 110VAC.

Yes, should do just fine. Both heads use the same tube (2211-25SLE is the same tube as 2214-25SLE for example) and the same connectors (Square white connector, round amphenol). Form factor is the only difference as far as I'm aware. They may come with a 20A or even 30A power connector - you can change it out to a 15A.

Edit: I think the correct model for the PSU is 2114 or 2111 not 22xx - Could be wrong there. I may have that the wrong way round... There are various models - just look for the connectors and the input voltage you need.

Thanks! Any idea why they add higher voltage/amperage connectors if they don't need them? is it just in case someone attaches one of the 45-65mw tubes to a 4SL PSU?

And yes, the proper model number for the PSU is 21xx, not 22xx. I was in a hurry.

The newer power supplies, and most of what you'll find on eBay are switch mode, so relatively efficient and lightweight compared to a linear equivalent.

Sam's laser FAQ has a bunch of schematics for a linear Argon laser power supply. Haven't tried any of them so I don't know how good they are. It's linear though, so expect it to be heavy and not very efficient. So yes, you certainly could build one with a bit of experience.

I know the variac / bridge rectifier / capacitor and a old heater will get the tube to lase : P . ( head had ignitor in it )


very very not recommended for actual running though ...

The tubes all have the same current ratings regardless of power output so it's not that. The PSUs are generally rated at 17A @ 110VAC so they can't really stick a 15A plug on it. I think I'm getting the 30A twistlock confused with the 20A version, so yes, likely either a 20A NEMA plug or a 20A twistlock is what they'll come with. Ideally you'd leave that on there and use it with a 20A outlet but it'll work just fine with a 15A NEMA on a 15A outlet.

Certainly not ideal, but it does the job for testing purposes right?
