Open AccessMeasurement and microscopic description of odd–even staggering of charge radii of exotic copper isotopes
Nuclear charge radii globally scale with atomic mass number A as A1∕3, and isotopes with an odd number of neutrons are usually slightly smaller in size than their even-neutron neighbours. This odd–even staggering...

QCW diode-side-pumped Nd:YAG ceramic laser with 247 W output power at 1123 nm
We demonstrate for the first time a diode-side-pumped quasi-continuous-wave (QCW) operation of a 1123 nm Nd:YAG ceramic laser. The single 1123 nm wavelength is acquired through precise coating. With a pump pow...
