Solid-state lasers require optical pumping; the most efficient method would be to use a narrow-line source at a suitable absorption frequency larger than the laser’s, but as close as possible. The ...

Breakthrough in PCSEL Optical Sensing Technology by Asahi Kasei Microdevices Enables 2 µm-Band Infrared Laser Generation TOKYO - April 9, 2026 - Asahi Kasei Microdevices Corporation (AKM), in ...

Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

Have you ever wished to drive microscopic matter along an arbitrarily tailored trajectory instead of just a circle? That's exactly what we set out to achieve.

An infrared laser could shrink sensing systems while enabling precise gas detection, opening the way for compact tools to ...

Why fast-response, non-contact temperature sensing is needed in biomedical research. How thin, transparent film is used to create the Seebeck effect to measure temperature. The instrumentation ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2024.240105, discusses a high-resolution tumor marker detection based on microwave photonics demodulated dual wavelength fiber laser ...
