Yb:YAG is an important diode-pumped laser crystal, better suited to diode pumping than traditional Nd-ion-doped laser materials. Compared with commonly used Nd:YAG, Yb:YAG has a broad diode-pump absorption band that effectively reduces laser-diode thermal-management requirements; the source sentence is truncated.
