Ytterbium – Yb:YAG is a very promising laser crystal and is more suitable for diode-pumping than the commonly used Nd-doped YAG crystals. Compared with the traditional Nd:YAG crystal, Yb:YAG crystal has a much wider absorption bandwidth to reduce thermal management of diode lasers. Yb:YAG emits typically at either 1030 nm (strongest line) or 1050 nm (ytterbium-doped gain media).  It is often used in powerful and efficient thin-disk lasers. Yb:YAG yttrium aluminium garnet crystal is expected to replace Nd:YAG crystal for high power diode-pumped lasers and other potential applications.
