Even Older Pulsed Argon

[Eidetic]

This TRW Instruments model 83A pulsed argon ion laser system arrived at the same time as the SP-162 just posted. No date on the label, but on the plasma tube is a sticker showing 1970 as the date of manufacture. Very simple system, especially the power supply. This is the second of this model in the archive. I'll have to remove the tube from the other one to see its date. My post describing it is here: https://www.photonlexicon.com/forums...rw+instruments
