Good day folks...
I'm playing around with some gas here in my shop, and obviously can't do blanking via TTL, so I need either a PCAOM or a galvo blanker...
I am running Argon and HeNe so I can do full color, but would be happy with single color just getting started.
Due to my very limited budget (read: non-existent) I'm going to be starting out full DIY with speaker galvos which I tested last night with some waveforms and can get decent enough results to approximate a laser oscilloscope.
Now - My HeNe PSU has a TTL line - which I believe I could use as a blanker... but I'm not sure.. Since its gas, I tend to think cranking the tube on and off rapidly would be bad news... Correct?
Next - PCAOM - I realize this is pretty much fossilized ancient history - but a quick ebay check yielded few results, and those were very expensive... Does anyone have a single color blanker they would part with cheaply so I could get my feet wet?
Also - can anyone point me in the right direction for more info on the "old school" setup using gas? Most everything I see is solid state... I found a few references to PCAOM and galvo blanking, but not a lot... not enough to learn much of anything.
I know the way to go is with SS diode tech.. but sorry, I'm a gas laser fan in my core...
Thanks for the help guys!
