Nd:YVO4
Nd: YVO4 tioata o se tasi o le tioata talimalo sili ona lelei leisa o loʻo i ai nei mo le diode leisa pamu leisa malo malo. O lona lapo'a fa'aoso fa'aoso fa'aoso i le lasing umi galu, maualuga absorption coefficient ma lautele absorption bandwidth i pamu umi galu, leisa maualuga fa'aoso fa'aleagaina faitoto'a fa'apea fo'i ma mea lelei fa'aletino, va'aia ma fa'ainisinia faia Nd: YVO4 o se tioata sili ona lelei mo le malosi maualuga, mautu ma tau aoga diode pamu lasers malo malo.
Fa'aaliga ma Fa'aoga
★ Low lasing paepae ma maualuga slope lelei
★ Fa'alagolago maualalo ile umi ole galu pamu
★ Tele fa'aoso fa'aoso fa'a'ese'esega fa'alava i fa'amauga umi galu
★ maualuga absorption i luga o le lautele pamu galu umi bandwidth
★ Optitically uniaxial ma birefringence lapopoa emits polarized leisa
★ Mo le tasi-faaumiumi-mode gaosiga ma mamanu faʻatusatusa
★ Diode leisa-pumped Nd: YVO4 leisa compact ma lona masani-faalua lanu meamata, mumu po o le lanumoana leisa o le a avea ma meafaigaluega lelei leisa o masini, meafaitino gaosi, spectroscopy, suʻesuʻega wafer, faʻaaliga malamalama, diagnostics faafomaʻi, lomitusi leisa ma isi sili ona salalau. talosaga
