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 faffadan amfani da shi azaman na'ura mai ninki biyu a cikin tsarin laser na Nd-doped don fitarwar Green/Ja, KTP kuma yana ɗaya daga cikin mahimman lu'ulu'u a cikin hanyoyin daidaitawa don fitowar da za a iya gani daga bayyane (600nm) zuwa tsakiyar IR (4500nm) saboda shaharar tushen da aka yi masa famfo, asali da jituwa na biyu na Nd: YALF ko Nd.
Ɗaya daga cikin aikace-aikacen da ya fi dacewa shine KTP OPO / OPA wanda ba shi da mahimmanci (NCPM) wanda aka yi amfani da shi ta hanyar lasers mai kunnawa don samun babban tasiri na juyawa.KTP OPO yana haifar da kwanciyar hankali na ci gaba da fitowar bugun jini na femto-biyu na 108 Hz maimaita ƙimar da milli-watt matsakaicin matakan wutar lantarki 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.
