Nd:YLF — Isithombe Esifakiwe se-Lithium Yttrium Fluoride esifakiwe

Nd:YLF - I-Nd-doped Lithium Yttrium Fluoride

Incazelo emfushane:

I-Nd:Ikristalu ye-YLF ingenye into ebaluleke kakhulu yokusebenza kwe-crystal laser ngemva kwe-Nd:YAG. I-crystal matrix ye-YLF inobude obufushane bokusikwa kokumuncwa kwe-UV, inqwaba yamabhendi okudlulisa ukukhanya, i-coefficient yezinga lokushisa elibi lenkomba ye-refractive, kanye nomphumela omncane welensi eshisayo. Ingqamuzana ilungele ukusebenzisa ama-ion ahlukahlukene omhlaba angavamile, futhi ingakwazi ukubona i-laser oscillation yenani elikhulu lamaza wamaza, ikakhulukazi amaza e-ultraviolet. I-Nd:Ikristalu ye-YLF inobubanzi bokumuncwa okubanzi, isikhathi eside sempilo ye-fluorescence, kanye ne-polarization ephumayo, ilungele ukumpompa kwe-LD, futhi isetshenziswa kakhulu kuma-lasers ashayayo naqhubekayo ezindleleni zokusebenza ezihlukahlukene, ikakhulukazi ekuphumeni kwemodi eyodwa, ama-laser e-Q-switched ultrashort pulse lasers. Nd: I-YLF crystal p-polarized 1.053mm laser kanye ne-phosphate neodymium glass 1.054mm laser wavelength match, ngakho-ke iyinto efanelekile yokusebenza ye-oscillator yohlelo lwenhlekelele yenuzi yengilazi ye-neodymium.

Izici

I-Nd:Ikristalu ye-YLF, eyaziwa nangokuthi i-Nd-doped lithium yttrium fluoride, iyikristalu ye-lithium yttrium fluoride ekhiqiza amalaser angu-1047nm no-1053nm. Izinzuzo eziyinhloko ze-Nd:YLF crystal yilezi: ububanzi bomugqa we-fluorescent omkhulu kakhulu, umphumela welensi eshisayo ephansi, ukusetshenziswa kwe-laser okuqhubekayo Umkhawulo wokukhanya ojabulisayo ophansi, i-polarization yemvelo, njll. Ngakho-ke, i-Nd:Ikristalu ye-YLF, i-neodymium-doped lithium yttrium fluoride iyikristalu ye-laser efanelekile ye-laser evaliwe nemodi. I-Nd:YLF crystal esiyihlinzekayo, i-Nd-doped lithium yttrium fluoride ekhuliswe indlela ye-Czochralsky, inganikeza i-Nd:YLF crystal rod noma i-Nd:YLF crystal plate ene-doping concentration ehlukile.
