Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Current gold‐standard endotoxin detection relies on Limulus Amebocyte Lysate (LAL) reagents, yet this approach suffers from unsustainable exploitation of Limulus resources. Here, we developed a fiber‐optic Surface‐enhanced Raman scattering (SERS) probe that enables highly sensitive endotoxin detection with drastically reduced LAL consumption.

Ultrasensitive Diamond Cantilever‐Based Optical Microphone
The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...
