Yb: YAG kristal

Yb: YAG bụ otu n'ime ihe ndị na-arụ ọrụ laser na-ekwe nkwa ma dabara adaba maka mgbapụta diode karịa usoro Nd-doped ọdịnala.E jiri ya tụnyere Nd: YAG crsytal, Yb: YAG kristal nwere nnukwu bandwidth absorption nke ukwuu iji belata ihe njikwa thermal chọrọ maka lasers diode, ogologo ọkwa elu-laser ogologo ndụ, okpukpu atọ ruo anọ na-agbadata thermal loading per unit pump power.Yb: YAG kristal na-atụ anya ka ọ dochie Nd: YAG kristal maka nnukwu ike diode-pumped lasers na ngwa ndị ọzọ nwere ike.
Ho: YAG kristal

Ho: YAG Ho³⁺ion nke etinyere n'ime kristal laser mkpuchi egosipụtala ọwa laser inter-manifold 14, na-arụ ọrụ n'ụdị nwa oge site na CW ruo na-ekpochi ọnọdụ.Ho: YAG na-ejikarị eme ihe dị ka ụzọ dị mma iji mepụta ikuku laser 2.1-μm site na⁵I₇-⁵I₈mgbanwe, maka ngwa dị ka laser remote sensing, ọgwụ ịwa ahụ, na pumping Mid-IR OPO's iji nweta 3-5micron emission.Sistemụ mgbapụta diode Direct, yana Tm: Fiber Laser pumped system egosipụtara arụmọrụ mkpọda dị elu, ụfọdụ na-abịaru nso oke usoro iwu.
Tm: YAP kristal

Tm doped kristal na-anabata ọtụtụ atụmatụ mara mma nke na-ahọpụta ha ka ọ bụrụ ihe a na-ahọrọ maka isi iyi laser steeti siri ike nwere ogologo ikuku ikuku na-emegharị gburugburu 2um.E gosipụtara na Tm: YAG laser nwere ike na-ege ntị site na 1.91 ruo 2.15um.N'otu aka ahụ, Tm: YAP laser nwere ike n'iji ya gee ntị nso si 1.85 ka 2.03 um. The quasi-atọ larịị usoro nke Tm: doped kristal chọrọ kwesịrị ekwesị pumping geometry na ezi okpomọkụ mmịpụta si arụ ọrụ mgbasa ozi.
Er:YSGG/Er,Cr:YSGG kristal

Ihe ndị na-arụ ọrụ sitere na Erbium doped Yttrium Scandium Gallium Garnet kristal (Er: Y3Sc2Ga3012 ma ọ bụ Er:YSGG), otu kristal, ka achọrọ maka diode gbanyere lasers steeti siri ike na-enwu na oke 3 µm.Er:YSGG kristal na-egosi nleba anya nke ngwa ha yana Er: YAG, Er:GGG na Er:YLF kristal.
Ebe: YAG kristal

Er: YAG bụ ụdị ọmarịcha 2.94 um laser kristal, nke a na-ejikarị na sistemụ ahụike laser na mpaghara ndị ọzọ.Er: YAG kristal laser bụ ihe kachasị mkpa nke laser 3nm, na mkpọda na arụmọrụ dị elu, nwere ike na-arụ ọrụ na laser okpomọkụ ụlọ, laser wavelength dị n'ime oke nke ìgwè nchekwa anya mmadụ, wdg 2.94 mm Er: YAG laser nwere. e ọtụtụ-eji ọgwụ ubi ịwa ahụ, akpụkpọ mma, eze ọgwụgwọ.
