Yttrium aluminum garnet (YAG) crystal

Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium, typically replaces yttrium in the crystal structure of the yttrium aluminum garnet (YAG), since they are of similar size. Generally the crystalline host is doped with around 1% neodymium by atomic percent. Advantages Of Nd:YAG：: • High gain; • Low threshold; • High efficiency; • Low loss at 1064nm; • Good thermal conductivity and thermal shock characteristics; • Mechanical strength; • High optical quality; • Material characteristics that allow for various modes of operation (CW, pulsed, Q-switched, mode locked). Applications: l Nd:YAG can produce blue laser with the frequency-doubling of 946nm; l Nd:YAG can be operated in a very high power laser up to kw level at 1064nm; l Nd:YAG can be Q-switched with Cr4+YAG directly; l Nd:YAG can be used for high power green laser for SHG@1064nm.
