LBO Crystal
LBO (LiB3O5) ụdị nke kristal optical na-enweghị linear nwere ezigbo nnyefe ultraviolet (210-2300 nm), ọnụ ụzọ laser mebiri emebi na nnukwu usoro ugboro abụọ na - arụkọ ọrụ ọnụ (ihe dị ka ugboro atọ nke kDP kristal). Ya mere, a na-ejikarị LBO arụpụta ọkụ ọkụ laser harmonic nke abụọ na nke atọ, ọkachasị maka lasars ultraviolet.
LBO nwere oghere ọnụnọ buru ibu na mpaghara nghọta, elu na-enweghị ahịrị, njiri kemịkalụ na usoro. Njirimara ndị a na-eme ka kristal a nwee ike ịrụ ọrụ parametric optical (OPO / OPA) yana otu ihe edoghị anya (NCPM).
Kpọtụrụ anyị maka usoro kachasị mma maka ngwa gị nke kristal LBO.
