Spin interactions in clean graphene are rather weak due to the weakness of spin-orbit coupling. However, graphene functionalization with adatoms and/or molecules permits to enhance both exchange and spin-orbit couplings in a controlled manner by a proper choice of adatoms, like 3d transition metal atoms to enhance exchange fields and heavy atoms (Pb or Bi) to enhance spin-orbit interactions.

Development of diode-pumped solid-state lasers with high energy/high average power with good beam quality are of increasing interest for various scientific and technological applications such as laser driven inertial fusion, pump source for optical parametric chirped-pulse amplification (OPCPA), laser shock peening to harden the metals, laser induced damage threshold measurement etc. To develop such systems, Yb–doped laser materials are used due to the simplest energy level structure and easy availability of diode lasers as pump sources, and are cooled down to cryogenic temperatures.
