Could someone update the Evil Overlord List? Peacocks are for-sure cheaper to keep than sharks, and we all know about prioritizing useful expenditures over intimidating decor.
Is it actually lasing or is it just fluorescence filtered by the microstructure? Definition of lasing entails nonlinear processes, the article seems to only indicate monochromaticity which can be achieved via linear filtering alone?
Additionally, nonlinear processes don’t immediately imply lasing either. It could be anharmonicity causing high order harmonics, which many biological materials will exhibit in response to intense laser sources[0]. In order to actually qualify as lasing you need to have evidence of coherent amplification.

I look forward to what tomorrow brings.
