Open Access3D laser nano-printing on fibre paves the way for super-focusing of multimode laser radiation
Multimode high-power laser diodes suffer from inefficient beam focusing, leading to a focal spot 10–100 times greater than the diffraction limit. This inevitably restricts their wider use in ‘direct-diode’ app...
