New class of laser wavemeter breaks the glass ceiling

The precise wavelength of a laser is important in numerous applications, but measuring changes of wavelength to one part in ten thousand million has been quite demanding. Our group has invented a new technique for doing such measurements based on the random scattering of laser light from a rough surface. This breakthrough could revolutionise the use of lasers in certain applications in quantum technologies and in healthcare.
