Default So I found a Spectra-Physics 106-1 laser...

As the title says, I found a 106-1 laser. It says the output is 20mW, but that's about all I know about it. There is no power source. I'm not sure what voltage/current requirements it has, but I'd like to play around with it. The only other info I have is that the positive wire is rated to 20kVDC. Anybody have any ideas? BTW, this laser was produced in 1985.

Pics would help.

The cathode filament will probably need around 3v and 25A. The starter circuit (if it's still with the laser) usually uses the same DC voltage as the tube, I'm not really sure what kind of voltage the starter itself kicks out, but its a few thousand volts. The tube usually uses around 100VDC in the smaller argons, anywhere from 4-10A.

Continuing ---- If the tube ignites, you need immediate current limiting because the arc shifts the tube to low impedance and it will draw almost unlimited current.
If you intend to experiment with your own power supply, you need to do a lot of reading on Sam's Laser Facts site and know how to handle high voltages.

Think Safety
