Potassium Titanyl Phosphate (KTiOPO4 kana KTP) KTP ndiyo inonyanya kushandiswa zvinhu zvefrequency kupetwa kaviri kweNd: YAG uye mamwe maNd-doped lasers, kunyanya kana simba remagetsi riri padanho rakaderera kana repakati.Parizvino, yakawedzera uye intra-cavity frequency yakapetwa kaviri Nd: lasers uchishandisa KTP yave yakasarudzika pombi sosi yeinooneka dhayi lasers uye tunable Ti: Sapphire lasers pamwe neawo amplifiers.Iwo zvakare anobatsira akasvibira masosi kune akawanda ekutsvagisa uye maindasitiri ekushandisa.
KTP iri kushandiswawo kusanganisa intracavity ye0.81µm diode uye 1.064µm Nd:YAG laser kugadzira mwenje weblue uye intracavity SHG yeNd:YAG kana Nd:YAP lasers pa1.3µm kugadzira mwenje dzvuku.
Pamusoro peakasarudzika maNLO maficha, KTP zvakare ine inovimbisa EO uye dielectric zvivakwa zvinofananidzwa neLiNbO3.Izvi zvinobatsira zvivakwa zvinoita kuti KTP ibatsire zvakanyanya kune akasiyana EO zvishandiso.
KTP inotarisirwa kutsiva LiNbO3 kristaro mune yakakura vhoriyamu yekushandiswa kweEO modulators, kana zvimwe zvakanaka zveKTP zvasanganiswa muaccount, senge yakakwira kukuvara kwechikumbaridzo, yakafara optical bandwidth (> 15GHZ), kupisa uye kugadzikana kwemuchina, uye kurasikirwa kwakaderera, nezvimwe. .
