Polariton laser

The earliest (known to me) proposal is by Yura and Hanamura[1]. People however remember better the works by A. Ĭmamoḡlu,[2][3] although he also quickly (like Yura) abandoned the topic for other problems.


it became more obvious to us that a “cavity-polariton laser” (if the concept had any meaning) could not be an ordinary laser.

Atom laser

The polariton laser approaches, from the light point of view, the problem of coherence that atoms approach from the matter point of view, with the concept of the atom laser.[4][5]

Controversies

What is exactly a polariton laser and how does it connect to a polariton BEC has been a recurrent question in the field. Leonid Butov has been one of the most vocal opponents of polariton condensates, which he sees as lasers instead.[6][7]
