Qui Gonn Jinns saber in that scene is outputting at least 321,260,978 KW. So yup. Note from the world of Star Wars gamemastering in old fashioned simulationism: most trauma from DEWS interaction with human or organic target is still kinetic, because penetration of even an inch or two immediately creates a pretty intense steam explosion. A "plasma bolt" that instantaneously burned through into the thoracic cavity would be messier than force feeding the target a hand grenade. More like a stick of dynamite. "Clean" laser weapons of science fiction would not be the reality; lasers powerful enough to cut off arms would be making meaty explosions. This sounds like a super duper efficient way to trauma, but it's still magic. That's a TON of energy - throwing an equivalent ball of explosive is easier and doesn't waste 90% of the emitter power on heating up air.
