    Kaliumka loo yaqaan 'Potassium Titanyl Phosphate' (KTiOPO4 ama KTP) KTP waa aaladda ugu badan ee loo isticmaalo soo noqnoqodka Nd: YAG iyo leysarka kale ee Nd-doped, gaar ahaan marka cufnaanta awoodda ay ku jirto heer hoose ama dhexdhexaad ah. Ilaa hadda, soo noqnoqoshada iyo ka-soo-baxa inta jeer ee labanlaabmay Nd: lasers-ka isticmaalaya KTP waxay noqdeen isha la doorbido ee laydhka la arki karo iyo Tiye: Sapphire lasers iyo sidoo kale kordhiyahooda. Waxay sidoo kale yihiin ilo cagaaran oo waxtar u leh cilmi baarisyo badan iyo codsiyada warshadaha.
    KTP waxaa sidoo kale loo isticmaalaa isku dhafka 'intracavity' ee 0.81µm diode iyo 1.064µm Nd: YAG laser si loo soo saaro iftiin buluug ah iyo intracavity SHG ee Nd: YAG ama Nd: YAP lasers at 1.3µm si loo soo saaro iftiinka cas.
    Marka lagu daro astaamaha NLO ee gaarka ah, KTP sidoo kale wuxuu leeyahay EO rajo leh iyo sifooyin dielectric oo u dhigma LiNbO3. Waxyaabahan faa'iidada leh waxay ka dhigayaan KTP mid waxtar badan u leh aaladaha kala duwan ee EO. 
    KTP waxaa lafilayaa inuu badalo madadaalada 'LiNbO3 crystal' ee codadka mugga leh ee modulators-ka EO, marka mudnaanta kale ee KTP lagu daro xisaabta, sida marinka waxyeelada badan, baaxada ballaadhan ee indhaha (> 15GHZ), xasiloonida kuleylka iyo farsamada, iyo luminta hoose, iwm .
    Noocyada ugu muhiimsan ee KTP Crystals :
    Conversion Beddelaad wax ku ool ah (1064nm SHG waxtarka beddelka ayaa ku saabsan 80%)
    Co Isuduwayaal fara badan oo aan toos ahayn (15 jeer ka badan KDP)
    Band Ballaadh ballaadhan oo ballaadhan iyo xagal yar oo socod-ka-bax ah
    Temperature Heerkul ballaadhan iyo baaxad ballaadhan oo ballaadhan
    Ivity Kuleylka kuleylka sareeya (2 jeer kan BNN crystal)
    Codsiyada:
    Ub Laablaab Laablaab (SHG) oo ah Las-yada loo yaqaan 'Nd-doped Lasers' ee wax soosaarka Cagaaran / Casaan
    Mix Isku-darka Joogtada ah (SFM) ee Nd Laser iyo Diode Laser ee Soosaarka Buluugga ah
    Urces Ilaha Qiyaasta (OPG, OPA iyo OPO) oo loogu talagalay Soosaarka Tooska ah ee 0.6mm-4.5mm
    Mod Isbeddelayaasha Qalabka Korantada (EO), Isbedelada Fikradaha, iyo Lamaanayaal Jihaynaya
    Wa Hirarka Hirarka indhaha ee qalabka isku dhafan ee NLO iyo EO a = 6.404Å, b = 10.615Å, c = 12.814Å, Z = 8
