A new solid-state laser produces 193-nm light for precision chipmaking and even creates vortex beams with orbital angular ...

Spatial coherence means that there is a well-defined beam with well-defined phase across it. For many lasers, the divergence of the laser beam is as low as 1–2 times the diffraction limit ...

Deep ultraviolet (DUV) lasers, known for their high photon energy and short wavelengths, are essential in various fields such ...

Generating X-rays that have the properties of laser light has been a long-standing goal for experimental science. Here we describe the emission of highly collimated, spatially coherent X-rays, at ...

Researchers from the Chinese Academy of Sciences recently achieved a breakthrough by creating a compact, solid-state laser ...
