    Potassium Titanyl Phosphate (KTiOPO4 ko KTP) KTP shine kayan da aka fi amfani dashi don mita ninki biyu na Nd:YAG da sauran lasers Nd-doped, musamman lokacin da ƙarfin ƙarfin yana kan ƙarami ko matsakaici.Ya zuwa yau, ƙarin mitar da ke cikin rami ya ninka Nd: Lasers masu amfani da KTP sun zama tushen bututun da aka fi so don les ɗin rini da ake iya gani da Ti: Sapphire Laser da kuma na'urorin haɓakarsu.Hakanan suna da amfani koren tushe don yawancin bincike da aikace-aikacen masana'antu.
    Hakanan ana amfani da KTP don haɗuwa da intracavity na 0.81µm diode da 1.064µm Nd: YAG Laser don samar da hasken shuɗi da intracavity SHG na Nd: YAG ko Nd: YAP lasers a 1.3µm don samar da haske ja.
    Baya ga keɓaɓɓen fasalulluka na NLO, KTP kuma yana da ƙwaƙƙwaran EO da kaddarorin dielectric waɗanda suke kwatankwacin LiNbO3.Waɗannan kaddarorin masu fa'ida suna sa KTP ke da amfani sosai ga na'urorin EO daban-daban.
    Ana sa ran KTP zai maye gurbin kristal LiNbO3 a cikin babban aikace-aikacen ƙarar EO masu daidaitawa, lokacin da aka haɗa sauran abubuwan da suka dace na KTP a cikin asusu, kamar babban lalacewa kofa, bandwidth mai faɗi mai faɗi (> 15GHZ), kwanciyar hankali na thermal da inji, da ƙarancin hasara, da sauransu. .
    Babban fasali na KTP Crystals:
    ● Ingantacciyar jujjuyawar mitar (1064nm SHG ingantaccen juzu'i shine kusan 80%)
    ● Manya-manyan ƙididdiga na gani marasa kan layi (sau 15 na KDP)
    ● Faɗin bandwidth na kusurwa da ƙananan kusurwar tafiya
    ● Faɗin zafin jiki da bandwidth na gani
    ● High thermal conductivity (sau 2 na BNN crystal)
    Aikace-aikace:
    ● Matsakaicin Sau biyu (SHG) na Lasers Nd-doped don Fitowar Kore/Ja
    ● Cakuda Frequency (SFM) na Nd Laser da Diode Laser don fitowar shuɗi
    ● Maɓuɓɓugan Mahimmanci (OPG, OPA da OPO) don 0.6mm-4.5mm Tunataccen Fitarwa
    ● Na'urar gani na Lantarki (EO) Modulators, Na'urar Canjawa, da Masu Haɗa kai
    ● Jagorar Wave Na gani don Haɗe-haɗen NLO da na'urorin EO a = 6.404Å, b=10.615Å, c=12.814Å, Z=8
