KTA Crystal
KTA (Kaliumta Titanyle Arsenate, KTiOAsO)4 ) waa buluug toosan oo aan toos ahayn oo la mid ah KTP oo Atom P lagu beddelay As. Waxay leedahay muuqaal wanaagsan oo aan toos ahayn iyo qalab elektaroonig ah, tusaale ahaan si aad u yar ayay u dhuuqdaa nuugista tirada baaxadda leh ee ah 2.0-5.0 µm, xagal ballaadhan iyo baaxad xaraarad, cabbir hooseeya.
Marka la barbardhigo KTP, faa iidooyinka ugu weyn ee KTA waxaa ka mid ah: mid aad u sarreeya oo aan isku xirnayn oo aan toos ahayn, hirarka IR-ka gooyo-dheer, iyo soo-jiidashada yar ee 3.5 µm. KTA sidoo kale waxay leedahay dhaqdhaqaaq yar oo ionic oo ka hooseeya kan KTP, taas oo keenta in laser sare uu khasaare soo gaarsiiyo.
KTA waxaa si aad ah loogu isticmaalaa arjiga Optical Parametric Oscillation (OPO) kaas oo siinaya awood tamar sare (50% ka sarreeya) shucaaca laser-ka ee looxaya adag.
