PPKTP Cystals

Nta:

• Customizable zaus hloov dua siab tshiab nyob rau hauv lub qhov rais pob tshab loj (0.4 - 3 µm)
• High optical puas pib rau durability thiab kev cia siab rau
• Loj nonlinearity (d33 = 16.9 pm / V)
• Crystal ntev mus txog 30 mm
• Loj apertures muaj raws li qhov kev thov (txog 4 x 4 mm2)
• Kev xaiv HR thiab AR txheej rau kev txhim kho kev ua haujlwm thiab kev ua haujlwm zoo
• Aperiodic poling muaj rau siab purity SPDC

Qhov zoo ntawm PPKTP

Kev ua haujlwm siab: lub sij hawm poling tuaj yeem ua tiav qhov kev hloov pauv ntau dua vim muaj peev xwm nkag mus rau qhov siab tshaj plaws nonlinear coefficient thiab tsis muaj kev taug kev ntawm qhov chaw.

Wavelength versatility: nrog PPKTP nws muaj peev xwm ua tau raws theem sib txuam hauv tag nrho cov pob tshab ntawm cov siv lead ua.

Customizability: PPKTP tuaj yeem tsim kho kom tau raws li cov ntawv thov tshwj xeeb.Qhov no tso cai rau kev tswj hwm bandwidth, qhov kub thiab txias qhov chaw, thiab tso zis polarizations.Tsis tas li ntawd, nws ua rau muaj kev sib cuam tshuam tsis sib xws uas cuam tshuam nrog cov nthwv dej.

Cov txheej txheem

Spontaneous parametric downconversion (SPDC) yog lub workhorse ntawm quantum optics, tsim ib tug entangled photon khub (ω1 + ω2) los ntawm ib tug input photon (ω3 → ω1 + ω2).Lwm daim ntawv thov suav nrog kev tsim cov xeev tsim, quantum tseem ceeb faib tawm thiab duab dab.

Thib ob harmonic tiam (SHG) muab ob npaug rau zaus ntawm lub teeb input (ω1 + ω1 → ω2) feem ntau siv los tsim lub teeb ntsuab los ntawm cov lasers zoo nyob ib ncig ntawm 1 μm.

Sum zaus tsim (SFG) tsim lub teeb nrog qhov sib npaug ntawm cov khoom siv hluav taws xob (ω1 + ω2 → ω3).Cov ntawv thov muaj xws li kev tshawb nrhiav upconversion, spectroscopy, biomedical imaging thiab sensing, thiab lwm yam.

Qhov sib txawv zaus (DFG) tsim lub teeb nrog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob (ω1 - ω2 → ω3), muab cov cuab yeej muaj txiaj ntsig rau ntau yam kev siv, xws li optical parametric oscillators (OPO) thiab Optical Parametric Amplifiers (OPA).Cov no feem ntau yog siv hauv spectroscopy, sensing thiab kev sib txuas lus.

Lub rov qab nthwv dej optical parametric oscillator (BWOPO), ua tiav kev ua haujlwm siab los ntawm kev faib cov twj tso kua mis photon mus rau pem hauv ntej thiab rov qab propagating photons (ωP → ωF + ωB), uas tso cai rau kev tawm tswv yim sab hauv hauv kev tawm tsam geometry.Qhov no tso cai rau muaj zog thiab compact DFG tsim nrog kev hloov pauv siab.
