Potaziyamu Titanyl Phosphate (KTiOPO4 kapena KTP) KTP ndiye zinthu zomwe zimagwiritsidwa ntchito kwambiri pakuwirikiza kawiri kwa Nd:YAG ndi ma lasers ena a Nd-doped, makamaka mphamvu ikakhala yotsika kapena yapakati.Mpaka pano, ma frequency owonjezera komanso amkati mwapang'onopang'ono owirikiza kawiri Nd: ma lasers omwe amagwiritsa ntchito KTP akhala gwero lokonda kupopera ma laser owoneka ndi utoto wa Ti: ma laser a safiro komanso ma amplifiers awo.Ndiwonso magwero obiriwira othandiza pazofufuza zambiri komanso ntchito zamakampani.
KTP ikugwiritsidwanso ntchito kusanganikirana kwa intracavity ya 0.81µm diode ndi 1.064µm Nd:YAG laser kupanga kuwala kwa buluu ndi intracavity SHG ya Nd:YAG kapena Nd:YAP lasers pa 1.3µm kuti apange kuwala kofiira.
Kuphatikiza pa mawonekedwe apadera a NLO, KTP ilinso ndi EO yodalirika komanso ma dielectric omwe amafanana ndi LiNbO3.Zopindulitsa izi zimapangitsa KTP kukhala yothandiza kwambiri pazida zosiyanasiyana za EO.
KTP ikuyembekezeka kulowa m'malo mwa kristalo wa LiNbO3 pakugwiritsa ntchito ma modulator a EO, pomwe zoyenerera zina za KTP ziphatikizidwa, monga kuwonongeka kwakukulu, bandwidth yotalikirapo (> 15GHZ), kukhazikika kwamafuta ndi makina, ndi kutayika kochepa, ndi zina zambiri. .
Zofunika Zazikulu za KTP Crystals:
● Kutembenuza kwafupipafupi (1064nm SHG kutembenuza bwino ndi pafupifupi 80%)
● Makanema akuluakulu owoneka bwino opanda mzere (kuwirikiza ka 15 kuposa a KDP)
● Bandiwidth yotakata ya angular ndi ngodya yaing'ono yoyenda
● Kutentha kwakukulu ndi mawonekedwe a bandwidth
● Kutentha kwapamwamba (kuwirikiza kawiri kuposa BNN crystal)
Mapulogalamu:
● Frequency Doubling (SHG) ya Nd-doped Lasers for Green/Red Output
● Frequency Mixing (SFM) ya Nd Laser ndi Diode Laser ya Blue Output
● Parametric Sources (OPG, OPA ndi OPO) ya 0.6mm-4.5mm Tunable Output
● Electrical Optical(EO) Modulators, Optical Switches, ndi Directional Couplers
● Optical Waveguides for Integrated NLO and EO Devices a=6.404Å, b=10.615Å, c=12.814Å, Z=8
