Li-cysts tsa PPKTP

Likaroloana:

• Phetoho ea maqhubu a ikhethileng ka har'a fensetere e kholo e pepeneneng (0.4 - 3 µm)
• High optical senya monyako bakeng sa durability le ho tšepahala
• Ho se lumellane ho hoholo (d33=16.9 pm/V)
• Bolelele ba kristale ho fihla ho 30 mm
• Metsu e meholo e fumanehang ha e kopa (ho fihla ho 4 x 4 mm2)
• Liaparo tsa boikhethelo tsa HR le AR bakeng sa ts'ebetso e ntlafetseng le katleho
• Aperiodic poling e fumaneha bakeng sa bohloeki bo phahameng ba spectral SPDC

Melemo ea PPKTP

Bokhoni bo phahameng: ho sebetsa ka nako le nako ho ka finyella katleho e phahameng ea ho fetola ka lebaka la bokhoni ba ho fumana coefficient e phahameng ka ho fetisisa e se nang moeli le ho ba sieo ha sebaka sa ho tsamaea.

Wavelength versatility: ka PPKTP hoa khoneha ho finyella ho bapisa mohato sebakeng sohle se pepeneneng sa kristale.

Customizability: PPKTP e ka etsoa enjenere ho fihlela litlhoko tse ikhethileng tsa lits'ebetso.Sena se lumella taolo holim'a bandwidth, boemo ba mocheso, le polarizations ea tlhahiso.Ho feta moo, e nolofalletsa litšebelisano tse se nang moeli tse kenyelletsang maqhubu a loantšanang.

Mekhoa e Tloaelehileng

Spontaneous parametric downconversion (SPDC) ke "workhorse" ea quantum optics, e hlahisang para e kopantsoeng ea photon (ω1 + ω2) ho tloha ho photon e le 'ngoe ea ho kenya (ω3 → ω1 + ω2).Lisebelisoa tse ling li kenyelletsa tlhahiso ea linaha tse hatisitsoeng, kabo ea senotlolo sa quantum le litšoantšo tsa ghost.

Moloko oa bobeli oa harmonic (SHG) o eketsa makhetlo a mabeli a khanya e kenang (ω1 + ω1 → ω2) hangata e sebelisetsoang ho hlahisa leseli le letala ho tloha ho li-lasers tse thehiloeng hantle ho pota 1 μm.

Sum frequency generation (SFG) e hlahisa leseli ka kakaretso ea maqhubu a mabone a kenang (ω1 + ω2 → ω3).Likopo li kenyelletsa tlhahlobo ea upconversion, spectroscopy, litšoantšo tsa biomedical le sensing, joalo-joalo.

Difference frequency generation (DFG) e hlahisa leseli ka maqhubu a lumellanang le phapang ea maqhubu a mabone a lebone la ho kenya (ω1 - ω2 → ω3), ho fana ka sesebelisoa se feto-fetohang bakeng sa mefuta e mengata ea likopo, tse kang li-oscillator tsa optical parametric (OPO) le li-amplifiers tsa optical parametric (OPA).Tsena li sebelisoa hangata ho spectroscopy, sensing le puisano.

The backward wave optical parametric oscillator (BWOPO), e finyella katleho e phahameng ka ho arola photon ea pompo ho ea pele le ka morao ea li-photon tse jalang (ωP → ωF + ωB), e lumellang maikutlo a arolelanoang ka hare ho geometry e hanyetsang.Sena se lumella meralo e matla le e kopaneng ea DFG e nang le ts'ebetso e phahameng ea phetoho.
