Juyin Juyawa
An fara gabatar da KTP azaman kristal NLO don tsarin Laser doped Nd tare da ingantaccen juzu'i. A ƙarƙashin wasu sharuɗɗa, an ba da rahoton ingantaccen juzu'i zuwa 80%, wanda ya bar sauran lu'ulu'u na NLO a baya.
Kwanan nan, tare da ci gaban laser diodes, KTP ana amfani dashi sosai azaman na'urorin SHG a cikin diode famfo Nd:YVO4 m Laser tsarin zuwa fitarwa kore Laser, da kuma yin Laser tsarin sosai m.
KTP Don OPA, Aikace-aikacen OPO
Baya ga fa'idar amfani da shi azaman na'ura mai ninki biyu a cikin tsarin Laser Nd-doped don fitarwar Green/Ja, KTP kuma yana ɗaya daga cikin mahimman lu'ulu'u a cikin hanyoyin daidaitawa don fitarwa mai iya gani daga bayyane (600nm) zuwa tsakiyar IR (4500nm) saboda shaharar tushen sa da aka yi famfo, asali da jituwa na biyu na Nd:YAG ko Nd:YLF Laser.
Ɗaya daga cikin aikace-aikacen da ya fi amfani shi ne KTP OPO/OPA wanda ba shi da mahimmancin lokaci (NCPM) wanda aka yi amfani da shi ta hanyar laser mai kunnawa don samun babban ƙarfin juyi. da matsakaicin matakan ƙarfin milli-watt a cikin sigina da abubuwan da ba su da aiki.
Pumped by Nd-doped Laser, KTP OPO ya samu sama da 66% juzu'i na jujjuyawa daga 1060nm zuwa 2120nm.
