Experiment uses Si waferNo cavity mirrors needed;the wafer acts as a Fabry- Perot etalon.
Why only now?“Early laser studies (13, 14) had briefly noted the possibility of the time-reversed process oflasing, but detailed theory and investigation of practical realizations began with (11) [their own theory paper].”
“Early laser studies”Hamel, Woerdman (1989). “Nonorthogonality of the longitudinal eigenmodes of a laser.” PRA 40, 2785.Discussing “vector” right and left-travelling longitudinal eigenmodes of a one-dimensional laser, in reaction to a paper by Siegman on the nonorthogonality of transverse modes.
The popular media took it and ran Public service announcement from Prof. A. D. Stone The Fox News article about our work initially quoted me saying that “...the creation of the anti- laser... has been one of the defining technological innovations of the past century.”I am not, in fact, an off-scale egotist. What I actually said was that the laser was a defining invention of the past century, not the anti-laser. (The article has now been fixed.)
