Nd YAG
Yasungulwa eminyakeni yamashumi ayisithupha ekhulwini elidlule, i-Nd:YAG ibilokhu futhi isaqhubeka nokuba yikristalu ye-laser esetshenziswa kakhulu yezinto zekristalu yesimo esiqinile.Imingcele yayo ye-laser iwukuvumelana okuhle phakathi kwamandla nobuthakathaka bomncintiswano wayo.Nd:Amakristalu e-YAG asetshenziswa kuzo zonke izinhlobo zamalaser wesifunda esiqinile.Uma kuqhathaniswa namanye amakristalu e-laser, impilo yayo ye-fluorescence iphindwe kabili kune-Nd:YVO4 , kanye ne-thermal conductivity nayo ingcono.
Izici Nezicelo
★ Ukulahlekelwa Okuphansi ku-1064 nm, Ikhwalithi Ephezulu Yokubona, Izakhiwo Ezinhle Zomshini kanye Nezishisayo
★ Ukuzuza Okuphezulu, I-Threshold Ephansi, Ukusebenza Okuphezulu
★ Ngenxa ye-symmetry ye-cubic kanye nekhwalithi ephezulu, i-Nd: YAG kulula ukuyisebenzisa ngemodi ye-TEM00
★ Khiqiza i-laser eluhlaza okwesibhakabhaka ene-frequency-double engu-946nm
★ Yiba Q-ushintshe nge Cr: YAG ngqo
★ Isetshenziswe ku-laser yamandla aphezulu kakhulu kuze kufike ezingeni le-KW

Siphinde futhi sihlinzeke ngezinduku ze-laser ze-Grooved Nd:YAG, ezingathuthukisa ikhwalithi yomugqa, zinciphise umphumela oshisayo, futhi zithuthukise ukusebenza kahle kwenduku e-grooved ngo-10-20%.
Ukuze uthole ulwazi olwengeziwe ngolunye uhlobo lwekristalu njenge-Nonlinear Crystal [BBO (Beta-BaB2O4), i-Potassium Titanium Oxide Phosphate (KTiOPO4 noma i-KTP)], i-Passive Q-Switch Crystal [Cr: YAG (Cr4+:Y3Al5O12)], i-EO Crystal [ Lithium Niobate (LiNbO3), BBO crystal], Birefringent Crystal [Yttrium Orthovanadate (YVO4), Calcite, Lithium Niobate (LiNbO3), High Temperature Form BBO (α-BaB2O4), Single Synthetic Crystal Quartz, Magnesium Fluoride] (MgF2) a quote, sicela ukhululeke ukuxhumana nathi.
