NEC GLG3053 Argon Laser help

[picses74]

Hello ,

Please I have NEC GLG3035 argon laser with GTL2401 tube , I dont know the connections and voltages , as I dont have the power supply but I'm planning to make one , Could someone has a idea about that
I think the filamint it 3.2V but I dont know the tube voltage ( The ignitor is present but not connected )

Thanks
Amr

Hi,

check out Sam's Laser FAQ:

https://www.photonlexicon.com/laserfaq/laseraps.htm

Most of the small Argon Ion Lasers are very similar, the filament voltage is between 2.5 and 3 volts ac with 25 amps, and the anode voltage is around 100v (90-110v) dc with max 10-12 amp. tube current.

It's possible to build your own P/S easily with modern parts.
You can find some hints how to do that, if you search for some ALC60X circuit diagrams.

Please share your experiences with us.

Cheers
Mike

Hello Mike

Thank God , I get it to work . I used an old PC power supply for the filament ( conencted the 3.2V ), Also I put 2 50v DC power supplies in series and connected the -ve to the filament and the igniter ground and the +ve to the ingiter +ve connection . After I supplied the filament with 3.2v for about a min. I switched on the 2 power supplies and then the laser worked
Do you believe I got this laser for 400EGP which is 8 US dollars
Thanks anyway
Amr

Don't forget the aircooling of the tube. The laserhead has top oder side-fans to get the heat away.
