    Potaziyamu Titanyl Phosphate (KTiOPO4 kapena KTP) KTP ndi chinthu chomwe chimagwiritsidwa ntchito mobwerezabwereza Nd: YAG ndi ma lasers ena a Nd-doped, makamaka mphamvu yamagetsi ikakhala yotsika kapena yapakatikati. Pakadali pano, mafupipafupi owonjezera komanso owonekera mkati amawirikiza kawiri Nd: lasers ogwiritsa ntchito KTP akhala njira yabwino yopopera ma lasers owoneka bwino ndikuwongolera Ti: Sapphire lasers komanso ma amplifiers awo. Amathandizanso magwero obiriwira pamafukufuku ambiri ndi ntchito zamakampani.
    KTP imagwiritsidwanso ntchito kuphatikizira kwa ma diode a 0.81µm ndi 1.064µm Nd: YAG laser kuti apange kuwala kwa buluu ndi intracavity SHG ya Nd: YAG kapena Nd: YAP lasers ku 1.3µm kuti apange kuwala kofiira.
    Kuphatikiza pa mawonekedwe apadera a NLO, KTP imalonjezanso EO ndi ma dielectric omwe ali ofanana ndi LiNbO3. Zinthu zopindulitsa izi zimapangitsa KTP kukhala yothandiza kwambiri pazida zosiyanasiyana za EO. 
    KTP ikuyembekezeka kulowa m'malo mwa LiNbO3 kristalo mu kuchuluka kwa ma modulators a EO, pomwe zofunikira zina za KTP zikaphatikizidwa, monga chiwopsezo chachikulu, bandwidth yozungulira (> 15GHZ), kukhazikika kwamatenthedwe, komanso kutayika pang'ono, ndi zina zambiri .
    Zinthu Zazikulu za Makandulo a KTP:
    ● Kutembenuka koyenera pafupipafupi (1064nm SHG kutembenuka kwabwino kuli pafupifupi 80%)
    ● Ma coefficients akulu opanda mzere (kasanu ndi kawiri kuposa KDP)
    ● Mawotchi akuluakulu ndi maulendo ang'onoang'ono oyenda
    ● Kutentha kotakata komanso mawonekedwe owonekera
    ● Kutentha kwakukulu (nthawi 2 kuposa BNN crystal)
    Mapulogalamu:
    ● Frequency Doubling (SHG) ya Nd-doped Lasers for Green / Red Output
    ● Kusakanikirana Kwafupipafupi (SFM) ya Nd Laser ndi Diode Laser ya Blue Output
    ● Zowonjezera za Parametric (OPG, OPA ndi OPO) za 0.6mm-4.5mm Tunable Output
    ● Modulators a Optical Optical (EO), Ma switch a Optical, ndi Maupangiri Olowera
    ● Ma Waveguides a Optical a Integrated NLO ndi EO Devices a = 6.404Å, b = 10.615Å, c = 12.814Å, Z = 8
