Potassium titanyl phosphate (PPKTP) nke a na-agbanye n'oge oge bụ kristal na-adịghị na mbara igwe nke nwere usoro pụrụ iche nke na-eme ka ngbanwe ugboro ugboro na-arụ ọrụ nke ọma site na quasi-phase-matching (QPM).Igwe kristal ahụ nwere ngalaba ndị ọzọ nwere nhụsianya na-enweghị isi, na-enyere QPM aka idozi esemokwu ahụ na-adịghị mma na mmekọrịta.Enwere ike ịhazi kristal ka ọ nwee arụmọrụ dị elu maka usoro ọ bụla na-adịghị adị n'ime oke nghọta ya.

Atụmatụ:

  • Ntugharị ugboro ole enwere ike ịhazi n'ime nnukwu windo nghọta (0.4 - 3 µm)
  • Ọnụ ụzọ mmebi anya dị elu maka ịdịte aka na ntụkwasị obi
  • Nnukwu anaghị adị n'ịntanetị (d33=16.9 pm/V)
  • Crystal ogologo ruo 30 mm
  • Nnukwu oghere dị mgbe a rịọrọ ya (ihe ruru 4 x 4 mm2)
  • Nhọrọ HR na mkpuchi AR maka ịrụ ọrụ na arụmọrụ ka mma
  • Ntụle n'oge dị maka ịdị ọcha SPDC dị elu

Uru nke PPKTP

Ịrụ ọrụ dị elu: poling nke oge ọ bụla nwere ike nweta nrụpụta ntụgharị dị elu n'ihi ikike ịnweta ọnụọgụ ọnụọgụ kachasị elu na enweghị nkwụsị nke oghere.

Ngbanwe nke ogologo ogologo: na PPKTP, ọ ga-ekwe omume iji nweta oge-nkọwa na mpaghara nghọta zuru oke nke kristal.

Nhazi: Enwere ike imezi PPKTP iji gboo mkpa ngwa ahụ akọwapụtara.Nke a na-enye ohere ijikwa bandwit, ọnọdụ okpomọkụ, na mpụta polarizations.Ọzọkwa, ọ na-enyere aka na-abụghị online mmekọrịta gụnyere counterpropagating ebili mmiri.
