Nd:YVO4 –Diode Pumped Solid-state Lasers
Ingcaciso yeMveliso
I-Nd: YVO4 inokuvelisa i-IR enamandla kwaye izinzile, eluhlaza, i-laser eluhlaza okwesibhakabhaka kunye noyilo lwe-Nd: YVO4 kunye neekristali eziphindwe kabini. Kwizicelo apho i-compact design ngakumbi kunye ne-single-longitudinal-mode output ifunekayo, i-Nd: YVO4 ibonisa iingenelo zayo ezithile ngaphezu kwezinye iikristale ze-laser ezisetyenziswa ngokuqhelekileyo.
Izinto eziluncedo kwi-Nd:YVO4
● Umda we-lasing ephantsi kunye nokusebenza kakuhle kwe-slope
● Umnqamlezo omkhulu ovuselelweyo wokukhutshwa kwamaza obude
● Ukufunxwa okuphezulu ngaphaya komda wokumpompa obanzi we-wavelength
● Optically uniaxial kunye enkulu birefringence ikhupha laser polarized
● Ukuxhomekeka okuphantsi ekumpompeni ubude bamaza kwaye kudla ngokubakho imveliso yemowudi enye
