The trick: substituting the printer's continuous wave lasers with faster, more powerful pulse lasers that had finally become consistent enough to record clear pictures.

But if you think that's about as cool as the carbon material can get, listen to this: It can also be used to make ultrashort-pulse lasers.

It can then release the light it absorbs in quick bursts that last a few femtoseconds each (with one femtosecond lasting one millionth of one billionth of a second), which is what ultrashort-pulse lasers do.

Whenever any of my Anytown subscribers want to transfer files amongst themselves, the operating cost to me approaches zero because (aside from the capital costs of building the network), the cost of transfering those files is basically the electricity it takes to pulse lasers over the fiber and keep the fans on the routers humming.

And all 192 lasers must produce the same shaped pulse in the same trillionths of a second.

Fast ignition also takes less powerful lasers, because the reaction rides on the energy contained in the pellet after the first pulse.
