This makes me wonder how a true laser beam would work against a lightsaber. A lightsaber blade may only be able to deflect a blaster bolt because they are made up of the same basic substance. A laser beam, on the other hand, may not be affected by a lightsaber blade in the same way; perhaps it could even pass right through it.

It'd be interesting to see this explored in the EU, but I know they're too busy rehashing the Jedi vs. Sith conflict for the nth time to explore actually intriguing topics and questions.
