Tahuri Auautanga
I whakauruhia a KTP hei karaihe NLO mo nga punaha laser doped Nd me te kaha o te hurihanga. I raro i etahi tikanga, i korerotia te pai o te huringa ki te 80%, ka mahue etahi atu tioata NLO ki muri.
I tata nei, me te whakawhanaketanga o nga diodes laser, kei te whakamahia whanuitia te KTP hei taputapu SHG i roto i te diode i maemaa Nd: YVO4 nga punaha laser totoka hei whakaputa i te laser matomato, me te hanga ano i te punaha laser kia tino pai.
KTP Mo OPA, OPO Tono
I tua atu i tana whakamahinga whanui hei taputapu rearua i roto i nga punaha laser Nd-doped mo te putanga Kakariki/Whero, ko te KTP tetahi o nga tioata tino nui i roto i nga puna tawhā mo te whakaputanga mai i te kitea (600nm) ki waenganui-IR (4500nm) na te rongonui o ona puna maemaa, ko te mea taketake me te tuarua o nga momo laser Nd:YAG, Nd:YLF ranei.
Ko tetahi o nga tono tino whai hua ko te KTP OPO/OPA kore-arohaehae (NCPM) e pupuhihia ana e nga laser tunable ki te whiwhi i te kaha o te huringa teitei. Ko te KTP OPO nga hua i roto i nga putanga pumau tonu o te pupuhi femto-tuarua o te 108 Hz reeti tukurua. me nga taumata hiko toharite miri-watt i roto i nga whakaputanga tohu me te mangere.
Maamaa e te Nd-doped lasers, kua whiwhi KTP OPO i runga ake i te 66% te pai o te huringa mo te whakaheke-whakahuri mai i te 1060nm ki te 2120nm.
Nga Kaihuri Hiko-Optical
Ka taea te whakamahi i te karaihe KTP hei modulators electro-optical. Mo etahi atu korero, tena koa whakapā atu ki o maatau miihini hoko.
