Hey there, so I’m not good with lasers and tube technology as of yet, but these look like lasers. They have a manufacture date code of January 1992. The numbers that stand out the most to me is LGR 7655. I looked it up and found lasers, but they were a totally different construction and date. Can someone help me identify the details of these components? A data sheet would be fantastic! Google is currently failing me.
Thank you!
Also, I held them so you could get an idea of the size.
