Scientists create anti-laser for a condensate of ultracold atoms

An international team of scientists developed the world's first anti-laser for a nonlinear Bose-Einstein condensate of ultracold atoms. For the first time, scientists have demonstrated that it is possible to absorb the selected signal completely, even though the nonlinear system makes it difficult to predict the wave behaviour. The results can be used to manipulate superfluid flows, create atomic lasers, and also study nonlinear optical systems. The study was published in Science Advances.
