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.
