Fraunhofer IAF Researchers Conduct First Successful Demonstration of Dual-Media NV Diamond Laser System

A team of researchers led by Dr. Jan Jeske at Fraunhofer Institute for Applied Solid State Physics (IAF) has developed a new sensor system using Laser Threshold Magnetometry (LTM). This system combines nitrogen-vacancy (NV) diamond and a laser diode in an optical resonator, marking a major breakthrough in magnetic field measurement for medical applications. This innovative system allows for the precise detection of extremely small magnetic fields, such as those generated by brain waves, opening up novel possibilities for medical diagnostics and treatment. The research, recently published in Science Advances, marks the first successful demonstration of a dual-media laser system, representing significant progress within the BMBF-funded NeuroQ project... read more
