KTP Crystal
Potassium Titanyl Phosphate (KTiOPO4 ama KTP) KTP waa shayga ugu badan ee loo isticmaalo labanlaabida inta jeer ee Nd:YAG iyo lasers-ka kale ee Nd-doped, gaar ahaan marka cufnaanta korantadu ay tahay heer hoose ama dhexdhexaad ah.Ilaa hadda, inta jeer ee dheeraadka ah iyo daloolka gudaha ayaa labanlaabmay Nd: lasers-ka isticmaalaya KTP waxay noqdeen isha bamgareynta ee la door biday ee leysarka dheeha ee muuqda iyo Ti: Sapphire lasers-ka la hagaajin karo iyo sidoo kale cod-weyneyahooda.Waxay sidoo kale yihiin ilo cagaaran oo faa'iido leh oo loogu talagalay cilmi-baarisyo badan iyo codsiyo warshadeed.
KTP waxa kale oo loo istcimaalay isku darka dhexda ee 0.81µm diode iyo 1.064µm Nd:YAG laser si loo dhaliyo iftiinka buluuga ah iyo dhexda u ah SHG ee Nd:YAG ama Nd:YAP lasers at 1.3µm si loo soo saaro iftiin cas.
Marka lagu daro sifooyinka NLO ee gaarka ah, KTP waxa kale oo ay leedahay EO rajo leh iyo sifooyin koronto oo u dhigma LiNbO3.Guryahaan faa'iidada leh ayaa KTP ka dhigaya mid aad waxtar u leh aaladaha kala duwan ee EO.
KTP ayaa la filayaa inay ku bedesho kristal LiNbO3 codsiga mugga weyn ee modulators EO, marka mudnaanta kale ee KTP lagu daro xisaabta, sida heerka burburka sare, bandwidth ballaaran ee indhaha (> 15GHZ), xasilloonida kuleylka iyo farsamada, iyo luminta hoose, iwm. .
Astaamaha ugu muhiimsan ee KTP Crystals:
● Beddelida soo noqnoqoshada hufan (1064nm SHG wax ku oolnimada beddelashadu waa qiyaastii 80%)
● Isku-xireyaasha indhaha ee waaweyn ee aan toosnayn (15 jeer ka badan KDP)
● Xagal baladhan oo xagal iyo xagal yar oo socod ah
● Heerkulka ballaaran iyo baaxadda muuqaalka
● Dhaqdhaqaaqa kulaylka sare (2 jeer ka badan BNN crystal)
Codsiyada:
● Soo noqnoqoshada Labanlaabka (SHG) ee Laser-ka Nd-doped ee soo-saarka Cagaaran/Casaanka
● Isku-dhafka soo noqnoqda (SFM) ee Nd Laser iyo Diode Laser ee soo-saarka buluugga ah
Ilaha Parametric (OPG, OPA iyo OPO) ee 0.6mm-4.5mm
● Korantada indhaha (EO) Modulators, Bedelayaasha indhaha, iyo isku xidhayaasha jihooyinka
● Tilmaamaha Wave-ga ee Isku-dhafka NLO iyo EO Aaladaha a=6.404Å, b=10.615Å, c=12.814Å, Z=8
