KTA Crystal
Ko te Potassium Titanyle Arsenate (KTiOAsO4), he karaihe KTA ranei, he karaihe whatu kore raina pai mo te tono Optical Parametric Oscillation (OPO).He pai ake nga whakarea whatu kore-raina me te hiko-a-hiko, he tino heke te whakaurunga i roto i te rohe 2.0-5.0 µm, whanui koki whanui me te paemahana, te iti o te dielectric.Na te iti o te kawe katote ka nui ake te paepae kino ki te KTP.
He maha nga wa ka whakamahia te KTA hei reo OPO / OPA mo te tukunga i roto i te awhe 3µm tae atu ki te karaihe OPO mo te whakangao-a-kanohi i te mana toharite teitei.
Āhuahira:
Puata i waenga i te 0.5µm me te 3.5µm
Te kaha o te mata kore-raina
Te whakaaetanga pāmahana nui
He iti ake te tohuruarua i te KTP ka iti ake te hikoi
He pai te whakakotahitanga whatu me te kore-raina
Paepae kino teitei o AR-paninga: >10J/cm² i te 1064nm mo te 10ns nga pupuhi.
AR-whakakikorua he iti te whakaurunga i te 3µm e waatea ana
He tohu mo nga kaupapa mokowhiti
