Nd:YVO4 -Diode Pumped Solid-state Lasers
Tlhaloso ea Sehlahisoa
Nd:YVO4 e ka hlahisa li-lasers tse matla le tse tsitsitseng tsa IR, tse tala, tse putsoa ka moralo oa Nd:YVO4 le likristale tse imenang habeli.Bakeng sa lits'ebetso tseo ho tsona ho hlokahalang moralo o kopaneng le tlhahiso ea mokhoa o le mong oa longitudinal, Nd:YVO4 e bonts'a melemo ea eona e ikhethang ho feta likristale tse ling tsa laser tse sebelisoang hangata.
Melemo ea Nd:YVO4
● Tsela e tlaase ea ho betla le ho sebetsa hantle ha matsoapo
● Mosi o molelele o fapanyetsanang ka bolelele ba maqhubu
● Ho monyela holimo ka bongata bo boholo ba maqhubu a maqhubu a pompang
● Optically uniaxial le e khōlō birefringence e ntša laser polarized
● Ho itshetleha ho tlase hodima ho pompa wavelength mme ho sekamela ho tlhahiso e le nngwe
