I-KTP Crystal
I-Potassium Titanyl Phosphate (KTiOPO4 noma i-KTP) i-KTP iyinto esetshenziswa kakhulu ukuphindwa kabili kabili kwe-Nd:YAG namanye ama-lases e-Nd-doped, ikakhulukazi uma ukuminyana kwamandla kukuleveli ephansi noma emaphakathi.Kuze kube manje, imvamisa eyengeziwe kanye ne-intra-cavity ephindwe kabili i-Nd:laser esebenzisa i-KTP isiphenduke umthombo wokumpompa okhethwayo wamalaser odayi abonakalayo kanye namalaser we-Ti:Sapphire ashintshwayo kanye nezikhulisi zawo.Futhi ziyimithombo eluhlaza ewusizo yocwaningo oluningi kanye nezicelo zemboni.
I-KTP futhi isetshenziselwe ukuxuba kwe-intracavity ye-0.81µm diode ne-1.064µm Nd:YAG laser ukukhiqiza ukukhanya okuluhlaza okwesibhakabhaka kanye ne-intracavity SHG ye-Nd:YAG noma i-Nd:YAP lasers ku-1.3µm ukukhiqiza ukukhanya okubomvu.
Ngaphezu kwezici ze-NLO ezihlukile, i-KTP iphinde ibe ne-EO ethembisayo kanye nezakhiwo ze-dielectric ezifana ne-LiNbO3.Lezi zakhiwo ezinenzuzo zenza i-KTP ibe usizo kakhulu kumadivayisi ahlukahlukene e-EO.
I-KTP kulindeleke ukuthi ithathele indawo yekristalu ye-LiNbO3 ekusetshenzisweni kwevolumu enkulu yamamoduli e-EO, lapho okunye ukufaneleka kwe-KTP kuhlanganiswa ku-akhawunti, njengomkhawulo womonakalo omkhulu, umkhawulokudonsa obanzi wokubona (>15GHZ), ukuzinza okushisayo nokokusebenza, nokulahlekelwa okuphansi, njll. .
Izici Eziyinhloko Zamakristalu e-KTP:
● Ukuguqulwa kwefrikhwensi okusebenzayo (1064nm SHG ukuguqulwa okusebenzayo kucishe kube ngu-80%)
● Ama-coefficients amakhulu angaqondile (okuphindwe ka-15 kune-KDP)
● Umkhawulokudonsa obanzi we-angular kanye ne-engeli encane yokuhamba
● Izinga lokushisa elibanzi kanye nomkhawulokudonsa we-spectral
● I-thermal conductivity ephezulu (izikhathi ezingu-2 kune-BNN crystal)
Izicelo:
● I-Frequency Doubling (SHG) ye-Nd-doped Lasers for Green/Red Output
● I-Frequency Mixing (SFM) ye-Nd Laser ne-Diode Laser ye-Blue Output
● Imithombo Yepharamitha (i-OPG, i-OPA ne-OPO) ka-0.6mm-4.5mm Okukhiphayo Okusebenzisekayo
● I-Electrical Optical(EO) Modulators, Optical Switches, kanye nama-Directional Couplers
● Ama-Optical Waveguides for Integrated NLO kanye ne-EO Devices a=6.404Å, b=10.615Å, c=12.814Å, Z=8
