Recently, a research team led by Professor Cai Wei and Professor Xu Jingjun from the School of Physical Sciences at Nankai University has experimentally confirmed for the first time the generation of polaritons, also known as Smith Purcell radiation, at the two-dimensional scale, and further demonstrated the ability of free electrons to regulate two-dimensional Smith Purcell radiation. The researc...
A project at Macquarie University has demonstrated a way to narrow the linewidth of a laser beam by a factor of over ten thousand.Published in APL Photonics, the technique offers a promising route toward ultra-narrow linewidth lasers for potential use in a wide range of pump-pulse systems.Laser linewidth measures how precisely a beam of light maintains its frequency and color purity, and narrow-li...
Barcelona-based photonics research center ICFO has announced the creation of its 13th Spin-off company, Shinephi. The official launch of the company was jointly made at the end of July by Dr. Roland Terborg (CEO and co-founder), Dr. Iris Cusini (CTO and co-founder) and ICREA Prof. at ICFO Valerio Pruneri (Technology Advisor and co-founder), accompanied by Dr. Silvia Carrasco, Vice Director of Inno...
SPIE, the international society for optics and photonics, has welcomed 92 new Senior Members from 19 countries. SPIE Senior Members are Society Members of distinction who are recognized for their professional experience and technical accomplishments, their active involvement with the optics community and with SPIE, and for significant performance that sets them apart from their peers.The newly rec...
Laser is considered a sharp sword that cuts iron like mud, but even sharper swords can have tricky moments. For example, in certain scenarios, there are materials with higher reflectivity, such as silver, copper, etc., known as "high reflection materials". High reflective materials have a low absorption rate for lasers, making them difficult to process and potentially causing equipment failure or ...
