KTA Crystal
KTA (Kaliumarangi Titanyle Arsenate, KTiOAsO4 Ko te karaihe kirikiri kore raina e rite ana ki te KTP kei te whakakapihia e te ngota P a As. He pai nga taonga o te raima kore me te kowhiri, tae atu ki te whakaheke nui i te roopu o te ropu o te 2.0-5.0 µm, te whanui whanui me te pāmahana huringa, te iti o te wa-dielectric.
Ina ki te KTP, ko nga painga matua o te KTA: ko te nuinga o te raihana kore-raarangi tuarua, he roa te tarai o te IR, he iti ake te whakauru i te 3.5 µm. I raro ano te KTA i te whakahaere ionik i raro ake nei i te KTP, ka puta ake te paepae kino kino o te laser.
Kei te tino whakamahia te KTA mo te tono Optical Parametric Oscillation (OPO) e kaha ana te huringa faafariutanga nui (ki runga ake i te 50%) o te hihiko laser rehu i roto i nga miihini totoka.
