Nd:YVO4
Nd:Ikristale yeYVO4 yenye yeyona kristale isebenzayo yelaser ekhoyo ngoku yediode laser impompo iilaser zesimo esomeleleyo. Inxalenye yayo enkulu evuselelweyo yokukhutshwa komnqamlezo kwi-lasing wavelength, i-coefficient yokufunxa ephezulu kunye ne-wide-absorption bandwidth kwi-pump wavelength, i-laser ephezulu eyenziwe ngumonakalo we-laser kunye neempawu ezilungileyo zomzimba, ezibonakalayo kunye nezomatshini zenza i-Nd: YVO4 ibe yikristale egqwesileyo yamandla aphezulu, ezinzile kwaye ixabiso elisebenzayo diode impompo eqinileyo-state lasers.
