Yup.

While it's hard to know the RAI of all charge effects, as they probably didn't account for PCs with pounce, RAW is pretty clear.

You wield this blade-like beam as if it were a scimitar... The blade deals 1d8 points of fire damage + 1 point per two caster levels (maximum +10).

Yes, you create something that is functionally a weapon and is wielded as a weapon that has damage dice of 1d8 (+1/2 caster level). Only the 1d8 gets multiplied, though.
