ʻO ka Potassium Titanyl Phosphate (KTiOPO4 a i ʻole KTP) KTP ka mea maʻamau i hoʻohana ʻia no ka pālua pinepine ʻana o Nd:YAG a me nā lasers Nd-doped ʻē aʻe, ʻoi aku ka nui o ka mana ma kahi haʻahaʻa a i ʻole ka pae waena.I kēia lā, ua hoʻopālua ʻia ka nui a me ka intra-cavity frequency Nd: lasers me ka hoʻohana ʻana i ka KTP i kumu puna maikaʻi loa no nā laser dye ʻike ʻia a me nā lasers tunable Ti: Sapphire a me kā lākou mau mea hoʻonui.He mau kumu ʻōmaʻomaʻo maikaʻi lākou no nā noiʻi a me nā noi ʻoihana.
Hoʻohana ʻia ʻo KTP no ka hui ʻana o intracavity o 0.81µm diode a me 1.064µm Nd:YAG laser e hoʻoulu i ke kukui polū a me intracavity SHG o Nd:YAG a i ʻole Nd:YAP lasers ma 1.3µm e hana i ke kukui ʻulaʻula.
Ma waho aʻe o nā hiʻohiʻona NLO kūʻokoʻa, loaʻa iā KTP nā mea hoʻohiki EO a me nā waiwai dielectric i hoʻohālikelike ʻia me LiNbO3.ʻO kēia mau waiwai maikaʻi e hoʻohana pono ai iā KTP i nā mea like ʻole EO.
Manaʻo ʻia ʻo KTP e pani i ka kristal LiNbO3 i ka noi nui o ka EO modulators, ke hui pū ʻia nā pono ʻē aʻe o KTP, e like me ka paepae pōʻino kiʻekiʻe, ka bandwidth optical ākea (> 15GHZ), ke kūpaʻa wela a me ka mechanical, a me ka poho haʻahaʻa, etc. .
Nā hiʻohiʻona nui o nā KTP Crystals:
● ʻO ka hoʻololi alapine kūpono (1064nm SHG ka hoʻololi ʻana ma kahi o 80%)
● Koefficient opua nonlinear nui (15 manawa o ka KDP)
● ʻO ka bandwidth angular ākea a me ke kihi hele wāwae liʻiliʻi
● Ka wela ākea a me ka bandwidth spectral
● Kiʻekiʻe thermal conductivity (2 manawa o ka BNN kristal )
Nā noi:
● Hoʻopālua pinepine (SHG) o Nd-doped Lasers no ka 'ōmaʻomaʻo/ʻulaʻula
● Hoʻohui pinepine (SFM) o Nd Laser a me Diode Laser no Blue Output
● Nā Punawai Parametric (OPG, OPA a me OPO) no 0.6mm-4.5mm Huna Hoʻopono
● Uila Optical(EO) Modulators, Optical Switch, a me Directional Couplers
● Nā alakaʻi nalu no nā NLO a me EO i hoʻohui ʻia a=6.404Å, b=10.615Å, c=12.814Å, Z=8
