KTP Crystal
KTP (KTiOPO4 ) bụ otu n'ime ihe ndị a na-ejikarị ngwa ngwa eji eme ihe na-adịghị mma. Iji maa atụ, a na-ejikarị ya ugboro abụọ nke Nd: ndị YAG lasers na ndị ọzọ Nd-doped lasers, ọkachasị ma ọ dịkarịrị ala. A na-ejikwa KTP eme ihe ebe nile dika OPO, EOM, ihe na-eduzi ihe nlere anya nke ihu na ihe ndi ozo.
KTP gosipụtara ezigbo ngwa anya, oke ngbasa ozi sara mbara, akụkụ nnabata sara mbara, obere mpaghara ije, na ụdị I na nke II enweghị nkwekọ oge dị egwu (NCPM) na oke mgbasa ihu. KTP nwekwara ọnụọgụ SHG dị elu dị elu (ihe dị ka okpukpu atọ karịa nke KDP) yana ọnụ ụzọ mmebi dị elu (> 500 MW / cm²).
Mkpo KTP nke na-agbadata mgbe niile na-ata ahụhụ site na ndokwasa na mmezi arụmọrụ ("isi awọ") mgbe ejiri ya n'oge usoro SHG nke 1064 nm n'ogo ike dị elu na ọnụego ugboro ugboro karịa 1 kHz. Maka ngwa-ike dị elu, WISOPTIC na-enye kristal nguzogide dị elu (HGTR) kTP kTP sitere na hydrothermal usoro. Kriks ndị dị otú a nwere ntakịrị ihe ntinye IR dị ala ma ọkụ ọkụ anaghị emetụta ya karịa KTP mgbe niile, yabụ zere nsogbu nke ike jikọtara ọnụ, arụmọrụ nke ọma, ndochi kristal, na ọgba aghara.
Dịka otu n'ime ndị na - ebuputa ihe dị mkpa nke KTP n'ahịa mba ụwa niile, WISOPTIC nwere ikike dị oke nke nhọrọ ihe, nhazi (ịmịpụta, mkpuchi), mmepụta oke, nnyefe ngwa ngwa na ogologo oge KTP dị mma. Ọ dịkwa mma ịkọ na ọnụahịa anyị nwere ezi uche.
