Crystal LN-Q gbanwere

Nkọwa dị mkpirikpi:

A na-eji LiNbO3 eme ihe n'ọtụtụ ebe dị ka modulators electro-optic na Q-switches maka Nd: YAG, Nd:YLF na Ti: Sapphire lasers yana modulators maka fiber optics.Tebụl na-esonụ depụtara nkọwapụta nke kristal LiNbO3 na-ahụkarị nke ejiri dị ka Q-switch nwere mgbanwe mgbanwe EO.

Ìhè ahụ na-agbasa na z-axis na mpaghara eletrik na-emetụta x-axis.Ọnụọgụ electrooptic nke LiNbO3 bụ: r33 = 32 pm/V, r31 = 10 pm/V, r22 = 6.8 pm/V na obere oge na r33 = 31 pm/V, r31= 8.6 pm/V, r22 = 3.4 pm/V na igwe eletrik dị elu.Ọkara-ebili mmiri voltaji: Vπ = λd / (2no3r22L), rc = (ne / no) 3r33-r13.LiNbO3 bụkwa ezigbo kristal acousto-optic ma jiri ya mee ihe maka ụda ụda elu (SAW) wafer na AO modulators.CASTECH na-enye kristal acoustic (SAW) ọkwa LiNbO3 na wafers, boules ndị a kpụrụ akpụ, ihe ndị emechara na ihe ndị emebere.
