Turbolasers vary in lethality factor. Therefore, your assumption is moot.To give you an idea, some Turbolaser based weapon systems, mounted on enormous starships, are powerful enough to utterly destroy a skyscraper with a single shot and I don't think that this kind of Turbolaser can be countered with a lightsaber.
You're right, he did it with his hand.
And lol @ an 120-foot long starship weighing less than a couple small cars max.
