Latest News
Nov 2025: Important new insights on stabilizing diamond Raman lasers just published in Optics Express.
Jun 2025: When it comes to linewidth narrowing, we show that Raman lasers are Brillouin lasers on steroids! Using a diamond Raman laser, we report linewidth compression by 10 thousand times, and predict values of 100 million are possible. 
Full publication is here and some commentary here.
Dec 2024: We've reported manipulation of a surface to the precision of one-hundredth of an atomic layer using a laser two-photon effect - on diamond of course! See articles on this work by Elsevier and ElectroOptics.com. We also show that this highly-practical technique enhances surface conductivity, which may be important for diamond semiconductors.

Jun 2024: Our "Stimulated Scattering Festival" with special guests Prof Zhenxu Bai (Hebei University of Technology) and Dr Arun Surendan (IIT Bombay). 
A fascinating day of sharing research and ideas.
Jan 2024: We show it's possible to etch and engineer the surface chemistry of a material with sub-monolayer accuracy using a laser beam only - no plasma or vacuum equipment required! Published in Applied Physics Letters, this work of PhD student Mojtaba Moshkani reveals yet another curious effect in diamond.
