@inproceedings{Steinhauer2021ConfirmationOS, title={Confirmation of stimulated Hawking radiation, but not of black hole lasing}, author={Jeff Steinhauer}, year={2021} }

Stimulated Hawking radiation in an analogue black hole in a Bose-Einstein condensate was reported seven years ago, and it was claimed that the stimulation was of the black hole lasing variety. The study was based on observation of rapidly-growing negative-energy waves. We find that the Hawking particles are directly observable in the experimental plots, which confirms the stimulated Hawking radiation. We further verify this result with new measurements. Also, the observed Hawking particles…

The theory of Hawking radiation can be tested in laboratory analogues of black holes by using light pulses in nonlinear fiber optics to establish artificial event horizons and observing that the probe stimulates Hawking radiation, which occurs in a regime of extreme non linear fiber optics where positive and negative frequencies mix.
