    I-Potassium Titanyl Phosphate (KTiOPO4 noma i-KTP) i-KTP yizinto ezisetshenziswa kakhulu ekuphindaphindweni kabili kwe-Nd: YAG namanye ama-lasers e-Nd-doped, ikakhulukazi lapho amandla kagesi esezingeni eliphansi noma eliphakathi nendawo. Kuze kube manje, imvamisa eyengeziwe neyangaphakathi kwe-cavity iphindwe kabili u-Nd: ama-lasers asebenzisa i-KTP abe ngumthombo wokuncamela okhethwayo wama-lasers wedayi abonakalayo ne-Ti tunable: i-lasappa lasers kanye ne-amplifiers yazo. Futhi iyimithombo eluhlaza ewusizo yezinhlelo eziningi zocwaningo nezimboni.
    I-KTP isetshenziselwa ukuhlanganiswa kwe-intracavity kwe-diode ye-0.81µm ne-1.064µm Nd: i-laser ye-YAG ukukhiqiza ukukhanya kwe-blue ne-intracavity SHG ye-Nd: YAG noma i-Nd: YAP lasers ku-1.3µm ukukhiqiza ukukhanya okubomvu.
    Ngaphezu kwezici ezihlukile ze-NLO, i-KTP nayo ine-EO ethembisayo nezakhiwo ze-dielectric ezifana neLiNbO3. Lezi zakhiwo ezisizakale zenza i-KTP isebenziseke kakhulu kumadivayisi e-EO ahlukahlukene. 
    I-KTP kulindeleke ukuthi ithathe isikhundla se-LiNbO3 crystal ekusetshenzisweni kwevolumu enkulu ye-modulators ye-EO, lapho okunye ukufaneleka kwe-KTP kuhlanganiswa ku-akhawunti, njengomkhawulo omkhulu womonakalo, umkhawulokudonsa obanzi we-optical (> 15GHZ), ukuzinza okushisayo nokwenziwe ngomshini, nokulahleka okuphansi, njll. .
    Izici Eziyinhloko Zamakhemikhali e-KTP:
    ● Ukuguqulwa kwemvamisa okusebenzayo (ukusebenza kahle kokuguqulwa kwe-1064nm SHG cishe kungu-80%)
    ● Ama-coefficients amakhulu angenawo umugqa (izikhathi eziyi-15 ze-KDP)
    ● Umkhawulokudonsa obanzi we-angular ne-angle yokuhamba encane
    ● Ukushisa okubanzi ne-bandwidth ye-spectral
    ● Ukuqhutshwa okuphezulu kokushisa (izikhathi ezi-2 ze-BNN crystal)
    Izicelo:
    ● Ukuphindaphinda kabili (SHG) kwe-Nd-doped Lasers ye-Green / Red Output
    ● Ukuxubeka Kwemvamisa (i-SFM) ye-Nd Laser ne-Diode Laser ye-Blue Output
    ● Imithombo ye-Parametric (i-OPG, i-OPA ne-OPO) yokuPhuma kokuLungiswa okungu-0.6mm-4.5mm
    ● Ama-Modulators we-Electrical Optical (EO), ama-Optical Switches, nama-Couple we-Directional
    ● Amagagasi we-Optical we-Integrated NLO ne-EO Devices a = 6.404Å, b = 10.615Å, c = 12.814Å, Z = 8
