Solid-state lasers articles from across Nature Portfolio

Electrically injected charges can effectively contribute to optical gain in perovskite light-emitting diodes under optical and electrical co-excitation.

Ultrahigh-efficiency and low-threshold yet tunable and compact laser devices are at the base of new functional devices. Here the authors harness a new temperature degree of freedom to realize a tunable photon-phonon collaboratively pumped laser.

We achieve milliwatt laser emissions at 1.06 µm wavelength from a 30 µm solid-state whispering-gallery-mode laser, constructed using Nd:YAG thin films obtained through carbon-implantation enhanced etching of a Nd:YAG crystal.

The frequency of coherent terahertz waves radiated from a single superconducting emitter can be electronically modulated on a chip with up to 40 GHz bandwidth, paving the way for high-data-rate and ultrafast terahertz wireless communications.

Allen Weeks, Director General of the Extreme Light Infrastructure European Research Infrastructure Consortium, talks to Nature Photonics about the founding and future of the high-power-laser facilities, and stimulating a resurgence of physics in new EU member countries.

The National Ignition Facility at Lawrence Livermore National Laboratory reported over 1.3 MJ output, representing 70% of both input laser energy and official ‘fusion ignition’. Operations manager, Bruno Van Wonterghem, delves into the optics and what to expect next.
