Ytterbium-doped Yttrium Aluminum Garnet Crystal (Yb:YAG)
Yb:YAG Crystal
Ytterbium-doped yttrium aluminum garnet (Yb: YAG) crystal is a promising laser material. It is more suitable for diode-pumped laser systems than other conventional doped YAG. Yb: YAG has a much wider absorption bandwidth, which reduces the thermal control requirements when designing diode lasers. It has a longer high laser energy level lifetime and a lower thermal load per unit pump power for 3-4 times. Yb: YAG crystals are expected to replace Er: YAG crystals for high power diode lasers and other related applications.
