    Potassium Titanyl Phosphate (KTiOPO4 lossis KTP) KTP yog cov khoom siv uas siv rau zaus ntau tshaj ntawm Nd: YAG thiab lwm yam Nd-doped lasers, tshwj xeeb tshaj yog thaum lub zog ceev muaj nyob rau theem qis lossis nruab nrab. Txog rau hnub tim, ntxiv thiab ntxiv rau hauv qhov chaw tso zis zaus ob npaug ntawm Nd: lasers siv KTP tau dhau los ua qhov xav tau rau lub tshuab nqus pom thiab zas Ti: Sapphire lasers raws li lawv cov tshuab muab suab. Lawv kuj yog cov khoom siv ntsuab ntsuab rau ntau cov ntaub ntawv tshawb fawb thiab kev lag luam.
    KTP tseem raug siv rau kev sib xyaw ntawm kev sib xyaw ntawm 0.81µm diode thiab 1.064µm Nd: YAG laser los tsim hluav taws xob xiav thiab intracavity SHG ntawm Nd: YAG lossis Nd: YAP lasers ntawm 1.3µm los tsim lub teeb liab.
    Ntxiv nrog rau NLO cov yam ntxwv tshwj xeeb, KTP kuj tseem muaj kev cog lus ntawm EO thiab dielectric uas muaj qhov sib piv rau LiNbO3. Cov khoom tau zoo ua rau KTP tsis tshua muaj txiaj ntsig rau ntau EO cov khoom siv. 
    KTP cia siab los hloov LiNbO3 siv lead ua hauv qhov ntau ntawm daim ntawv thov ntawm EO modulators, thaum lwm cov haujlwm zoo ntawm KTP tau muab tso ua ke rau hauv tus account, xws li kev puas tsuaj siab, qhov dav dav bandwidth (> 15GHZ), thermal thiab mechanical stability, thiab poob qis, thiab lwm yam. Cov.
    Cov Tseem Ceeb Ntawm KTP Muaju :
    ● Kev hloov pauv ntau zaus (1064nm SHG hloov dua siab tshiab siv hluav taws xob yog li 80%)
    ● Cov coefficients nonlinear loj loj (15 npaug ntawm KDP)
    Width Wide angular bandwidth thiab cov kaum kev taug kev me
    ● Tshaj qhov kub thiab cov bandwidth
    Thermal High thermal conductivity (2 npaug ntawm BNN siv lead ua)
    Daim ntaub ntawv:
    ● Ntau zaus Doubling (SHG) ntawm Nd-doped Lasers rau Qhov Pom Qhov Tso Tawm Tshiab / Liab
    Kev ntsuas qhov sib xyaw ua ke (SFM) ntawm Nd Laser thiab Diode Laser rau Qhov Tawm Xiav
    ● Parametric Qhov Chaw (OPG, OPA thiab OPO) rau 0.6mm-4.5mm Tunable Output
    ● Cov Hluav Taws Xob Hluav Taws Xob (EO) Cov Hluav Taws Xob, Kev Pauv Hluav Taws Xob, thiab Cov Ncauj Khoom Sib Txuas
    Wave Optical Waveguides rau Kev Koom Tes nrog NLO thiab EO Ntaus a = 6.404Å, b = 10.615Å, c = 12.814Å, Z = 8
