Nd: YVO4 –Diode Yavomye Ikomeye-ya Laser

Ibisobanuro bigufi:

Nd: YVO4 nimwe mumikorere ya laser yakira neza kristal iriho ubu kuri diode laser-pompe ikomeye-ya lazeri. Nd: YVO4 ni kristu nziza cyane kubububasha buhanitse, butajegajega kandi buhendutse bwa diode yavomye bikomeye-lazeri.

Ibisobanuro ku bicuruzwa

Nd: YVO4 irashobora kubyara imbaraga kandi zihamye IR, icyatsi, ubururu bwubururu hamwe nigishushanyo cya Nd: YVO4 hamwe na kristu inshuro ebyiri. Kuri porogaramu zirimo igishushanyo mbonera cyinshi hamwe nuburyo bumwe-burebure-busohoka bukenewe, Nd: YVO4 yerekana ibyiza byayo kurenza izindi zikoreshwa cyane na laser kristal.

Ibyiza bya Nd: YVO4

● Intambwe ntoya kandi ikora neza
● Imyuka minini itera imyuka yambukiranya igice ku burebure bwumurongo
Kwinjira cyane hejuru ya pompe yagutse yumurambararo
● Mubyukuri uniaxial kandi nini birefringence isohora laser
Kwishingikiriza kuri pompe yumurambararo kandi bikunda gusohoka muburyo bumwe
