Ama-cysts we-PPKTP

Izici:

• Ukuguqulwa kwemvamisa okwenziwa ngendlela oyifisayo ngaphakathi kwewindi elikhulu elibonisa ngale (0.4 – 3 µm)
• High optical umonakalo umkhawulo wokuqina nokuthembeka
• I-nonlinearity enkulu (d33=16.9 pm/V)
• Ubude be-Crystal bufika ku-30 ​​mm
• Izimbobo ezinkulu ezitholakalayo uma zicelwa (kufika ku-4 x 4 mm2)
• Izingubo zokuzikhethela ze-HR ne-AR zokuthuthukisa ukusebenza nokusebenza kahle
• I-aperiodic poling iyatholakala ngokuhlanzeka okuphezulu kwe-spectral SPDC

Izinzuzo ze-PPKTP

Ukusebenza kahle okuphezulu: ukuvota ngezikhathi ezithile kungafinyelela ukusebenza kahle okuphezulu kokuguqulwa ngenxa yekhono lokufinyelela i-coefficient ephezulu kakhulu engaqondile kanye nokungabikho kokuhamba kwendawo.

I-Wavelength versatility: nge-PPKTP kungenzeka ukufeza ukufanisa isigaba kuso sonke isifunda esingafihli sekristalu.

Ukwenza ngendlela oyifisayo: I-PPKTP ingahlelwa ukuze ihlangabezane nezidingo eziqondile zohlelo lokusebenza.Lokhu kuvumela ukulawula umkhawulokudonsa, indawo yokushisa, nokuhlukaniswa kokuphumayo.Ngaphezu kwalokho, inika amandla ukusebenzisana okungaqondile okubandakanya amaza aphikisanayo.

Izinqubo Ezijwayelekile

Ukuguqulwa okuzenzakalelayo kwe-parametric downconversion (SPDC) iyihhashi lokusebenza le-quantum optics, ekhiqiza ipheya ye-photon eboshwe (ω1 + ω2) kusuka ku-photon eyodwa yokufaka (ω3 → ω1 + ω2).Ezinye izinhlelo zokusebenza zifaka ukukhiqizwa kwezifunda ezikhanyiwe, ukusatshalaliswa kokhiye we-quantum kanye ne-ghost imaging.

Isizukulwane sesibili se-harmonic (SHG) siphinda kabili imvamisa yokukhanya okokufaka (ω1 + ω1 → ω2) evame ukusetshenziselwa ukukhiqiza ukukhanya okuluhlaza kumalaser amiswe kahle azungeze u-1 μm.

I-Sum frequency generation (SFG) ikhiqiza ukukhanya ngesamba semvamisa yezinkambu zokukhanya zokufaka (ω1 + ω2 → ω3).Izinhlelo zokusebenza zifaka ukutholwa kokuguqulwa, i-spectroscopy, i-biomedical imaging kanye nokuzwa, njll.

I-Difference frequency generation (DFG) ikhiqiza ukukhanya ngobuningi obuhambisana nomehluko wemvamisa yezinkambu zokukhanya zokufakwayo (ω1 – ω2 → ω3), ihlinzeka ngethuluzi eliguquguqukayo lezinhlobonhlobo zezinhlelo zokusebenza, njengama-optical parametric oscillator (OPO) kanye ama-amplifiers optical parametric (OPA).Lezi zivame ukusetshenziswa ku-spectroscopy, ukuzwa nokuxhumana.

I-backward wave Optical parametric oscillator (BWOPO), ifinyelela ukusebenza kahle okuphezulu ngokuhlukanisa i-pump photon ibe ama-photon asakazayo aya phambili nangemuva (ωP → ωF + ωB), okuvumela impendulo esabalaliswe ngaphakathi kujometri ephikisanayo.Lokhu kuvumela imiklamo eqinile futhi ehlangene ye-DFG enamandla okuguqulwa okuphezulu.

Ulwazi loku-oda

Nikeza ulwazi olulandelayo ukuze uthole ikhwothi:

• Inqubo efiselekayo: okokufaka ubude begagasi nobude begagasi lokukhiphayo
• I-polarizations yokokufaka nokuphumayo
• Ubude bekristalu (X: kufika ku-30 ​​mm)
• Imbobo yokubona (W x Z: kufika ku-4 x 4 mm2)
• I-AR/HR-coatings
