I have read the paper

Theoretical Study of Population Inversion in Graphene under Pulse Excitation. A. Satou, T. Otsuji and V. Ryzhii. Jpn. J. Appl. Phys. 50 no. 7, pp. 070116-070116-4 (2011).

Can a graphene laser really be made?

Hi ehsan. Welcome to Physics.SE. Can you provide us a referenced link regarding the paper which you claim? – Waffle's Crazy Peanut Apr 17 '13 at 13:25

1 Answer 1

The paper abstract indicates that a graphene laser could indeed (at least in principle) be made.

If you want to build a graphene laser yourself, I would first suggest you become proficient at fabricating graphene. The skills involved in that should help clarify what the issues would be in building such a laser.

And anyway, why do you want to build this? What's wrong with current lasers that graphene would solve?
