KTP — Hoʻopālua pinepine ʻia o nā Laser Nd:yag a me nā Lasers Nd-doped ʻē aʻe
Hōʻike huahana
ʻO KTP ka mea maʻamau i hoʻohana ʻia no ka pālua pinepine ʻana o nā lasers Nd:YAG a me nā lasers Nd-doped ʻē aʻe, ʻoi aku ka nui o ka mana haʻahaʻa a i ʻole.
Nā pono
● 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 )
● ʻAʻohe wai
● Ka liʻiliʻi liʻiliʻi like ʻole
● ʻO ka ʻili i hoʻomaʻamaʻa maikaʻi ʻia
● ʻAʻohe decomposition ma lalo o 900°C
● Mechanically paʻa
● Hoʻohālikelike ke kumu kūʻai haʻahaʻa me BBO a me LBO
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 Optical no nā NLO a me EO i hoʻohui ʻia
Hoʻololi pinepine
Ua hoʻokomo mua ʻia ʻo KTP ma ke ʻano he aniani NLO no nā ʻōnaehana laser doped Nd me ka maikaʻi hoʻololi kiʻekiʻe.Ma lalo o kekahi mau kūlana, ua hōʻike ʻia ka hoʻololi ʻana i ka 80%, e waiho ana i nā kristal NLO ʻē aʻe ma hope.
I kēia mau lā, me ka hoʻomohala ʻana i nā diodes laser, hoʻohana nui ʻia ʻo KTP e like me nā mea SHG i ka diode pumped Nd: YVO4 ʻōnaehana laser paʻa e hoʻopuka i ka laser ʻōmaʻomaʻo, a no ka hana ʻana i ka ʻōnaehana laser paʻa loa.
KTP No OPA, OPO Noi
Ma waho aʻe o kāna hoʻohana ākea ma ke ʻano he mea pālua pinepine i nā ʻōnaehana laser Nd-doped no ka puka ʻōmaʻomaʻo/ʻulaʻula, ʻo KTP kekahi o nā kristal koʻikoʻi loa i nā kumu parametric no ka hoʻopuka tunable mai ka ʻike ʻia (600nm) a i ka waena-IR (4500nm) ma muli o ke kaulana o kāna mau puna puna, ʻo ka harmonic kumu a me ka lua o kahi lasers Nd:YAG a i ʻole Nd:YLF.
ʻO kekahi o nā noi pono loa, ʻo ia ka KTP OPO/OPA i hoʻohālikelike ʻole ʻia (NCPM) KTP OPO/OPA e nā laser tunable no ka loaʻa ʻana o ka hoʻololi kiʻekiʻe. a milli-watt awelika pae mana ma nā hōʻailona a me nā mea hoʻopuka idler.
Pumi ʻia e nā lasers Nd-doped, ua loaʻa iā KTP OPO ma luna o 66% ka hoʻololi ʻana i ka pono no ka hoʻololi ʻana mai 1060nm a i 2120nm.
Electro-Optical Modulators
Hiki ke hoʻohana ʻia ke aniani KTP e like me nā modulators electro-optical.No ka ʻike hou aku, e ʻoluʻolu e kelepona i kā mākou mea kūʻai aku.
