CNT laser

I wanna see if it is possible to make laser with CNT (carbon nano tube) (Quantum wire) or carbon nano torus.
As you know we can use CNT as an E beam gun if we apply an external field.
 

CNT laser

I think it is impossible because as you know field emission is not related to lasing in laser we need exactly the same photons not electrons..
I mean the same f,p,v,...
