I believe it was used in Orlandos run?
lemme look into my wonderlibrary with this one!
So, it kept appearing a little number of times more:
-First Rucka's run, amazons were using it to heal Io after she was attacked by Ares
-Second Rucka's run, not a ray, but some kinda "purple bath" is used to heal Steve Trevor wounds during Year One
Did a quick visual overview on Orlando's issues, but couldn't find anything, so I supose that if the purple ray appeared, it was just mentioned? there may be other non-Wondy canon comics too
