In the Wookieepedia article on blaster technology, lasers - in the context of true electromagnetic beams - are mentioned to be archaic, suggesting they existed in Star Wars military history.

What records of true laser weaponry are there?
Legends answer preferred, since the article that contains the references are from Legends.
