KTP — Igbohunsafẹfẹ Ilọpo meji Ninu Nd: yag Lasers Ati Awọn Lasers Nd-doped miiran
ọja Apejuwe
KTP jẹ ohun elo ti o wọpọ julọ fun ilopo igbohunsafẹfẹ ti Nd: YAG lasers ati awọn lasers Nd-doped miiran, pataki ni iwuwo kekere tabi alabọde.
Awọn anfani
● Iyipada igbohunsafẹfẹ ti o munadoko (iṣiṣe iyipada SHG 1064nm jẹ nipa 80%)
● Àwọn olùsọdipúpọ̀ ìpìlẹ̀ tí kò láfiwé (ìlọ́po mẹ́ẹ̀ẹ́dógún ti KDP)
● Bandiwidi angular ti o gbooro ati igun gigun kekere
● Iwọn otutu ti o gbooro ati bandiwidi iwoye
● Imudara igbona giga (awọn akoko 2 ti okuta kristali BNN)
● Ọrinrin ọfẹ
● Imudara ibaamu ti o kere julọ
● Super-didan opitika dada
● Ko si ibajẹ labẹ 900°C
● Mechanical idurosinsin
● Iye owo kekere ni afiwe pẹlu BBO ati LBO
Awọn ohun elo
● Ilọpo meji (SHG) ti Awọn Lasers Nd-doped fun Alawọ ewe/Ijade Pupa
● Dapọ Igbohunsafẹfẹ (SFM) ti Nd Laser ati Diode Laser fun Blue Output
● Awọn orisun Parametric (OPG, OPA ati OPO) fun 0.6mm-4.5mm Imujade Tunable
● Itanna Optical (EO) Modulators, Awọn Yipada Opiti, ati Awọn Olukọni Itọsọna
● Awọn Itọsọna Wave Optical fun NLO Ijọpọ ati Awọn Ẹrọ EO
Iyipada Igbohunsafẹfẹ
KTP ni akọkọ ṣe afihan bi okuta NLO fun awọn ọna ṣiṣe laser doped Nd pẹlu ṣiṣe iyipada giga. Labẹ awọn ipo kan, ṣiṣe iyipada ni a royin si 80%, eyiti o fi awọn kirisita NLO miiran silẹ sẹhin.
Laipẹ, pẹlu idagbasoke ti awọn diodes lesa, KTP ti wa ni lilo pupọ bi awọn ẹrọ SHG ni diode fifa soke Nd:YVO4 awọn ọna laser to lagbara lati ṣe agbejade lesa alawọ ewe, ati tun lati jẹ ki eto ina lesa jẹ iwapọ pupọ.
KTP Fun OPA, Awọn ohun elo OPO
Ni afikun si lilo jakejado rẹ bi ẹrọ ilọpo meji igbohunsafẹfẹ ni awọn eto laser Nd-doped fun iṣelọpọ alawọ ewe / Pupa, KTP tun jẹ ọkan ninu awọn kirisita pataki julọ ni awọn orisun parametric fun iṣelọpọ itusilẹ lati han (600nm) si aarin-IR (4500nm) nitori olokiki ti awọn orisun fifa soke, ipilẹ ati irẹpọ keji ti Nd:YAG tabi Nd:YLF lasers.
Ọkan ninu awọn ohun elo ti o wulo julọ ni ipele ti kii ṣe pataki ti o baamu (NCPM) KTP OPO / OPA fifa nipasẹ awọn lasers tunable lati gba iṣẹ-ṣiṣe iyipada ti o ga julọ. Awọn abajade KTP OPO ni awọn abajade ilọsiwaju ti o duro ti femto-second pulse of 108 Hz repetition rate ati awọn ipele agbara apapọ milli-watt ninu ifihan mejeeji ati awọn abajade alaiṣẹ.
Ti fa nipasẹ awọn lasers Nd-doped, KTP OPO ti gba loke 66% ṣiṣe iyipada fun iyipada-isalẹ lati 1060nm si 2120nm.
