Fa'amatalaga o oloa

Nd: YVO4 e mafai ona gaosia IR mamana ma mautu, lanu meamata, lanumoana lasers ma le mamanu o le Nd: YVO4 ma tioata faaluaina taimi. Mo talosaga o lo'o mana'omia ai le fa'ata'ita'iga sili atu ma le fa'aogaina o le tasi-longitudinal-mode, Nd: YVO4 o lo'o fa'aalia ai ona fa'amanuiaga fa'apitoa nai lo isi tioata fa'aoga masani.

Tulaga lelei o Nd:YVO4

● maualalo lasing paepae ma maualuga slope lelei
● Lapo'a fa'aoso fa'aoso fa'a'ese'esega fa'alava i fa'amauga umi galu
● High absorption i luga o le lautele o le pamu o le galu umi bandwidth
● Optitically uniaxial ma birefringence lapopoa emits polarized leisa
● Fa'alagolago maualalo ile umi ole galu ma fa'asolosolo ile fa'aogaina o le tasi auala
