| | | | | | Intracavity-doubled green lasers within thousands of laboratories have been quiet for years without anyone knowing why. The answer is the opposite of the obvious one: A nonlinear crystal makes every mode noisier, but the total goes quiet anyway. |

| | | | | | No drug is approved to speed nerve regeneration for peripheral nerve injury, but four decades of research have established 780-nm continuous-wave photobiomodulation (PBM) as a validated, noninvasive treatment for significant motor recovery. We invite industrial partners to bring a translation-ready platform into clinical use. |

| | | | | | A misconception about quantum dot lasers (QDLs) is they’re poised to replace indium phosphide (InP) technology. But InP externally modulated lasers (EMLs) will continue serving optical networking and datacom applications, while QDLs emerge for applications that require power efficiency, thermal resilience, and integration density. |
