New research shows that laser spectral linewidth is classical-physics phenomenon https://phys.org/news/2020-07-laser-spectral-linewidth-classical-physics-phenomenon.html quote "As we have explained in this study, there is a simple, easy-to-understand derivation of the laser spectral linewidth, and the underlying classical physics proves the quantum-physics attempt of explaining the laser spectral linewidth hopelessly incorrect. This result has fundamental consequences for quantum physics." end quote
Perhaps this points to a new kind of physics which is a synthesis of classical and quantum physics. Harry
