KTP — Inta jeer ee Labanlaabka Nd: yag Lasers iyo Laysarada kale ee Nd-doped
Sharaxaada Alaabta
KTP waa shayga ugu badan ee loo isticmaalo labanlaabida soo noqnoqda ee Nd:YAG lasers iyo lasers-ka kale ee Nd-doped, gaar ahaan cufnaanta awoodda hoose ama dhexdhexaadka ah.
Faa'iidooyinka
● Beddelida soo noqnoqoshada hufan (1064nm SHG wax ku oolnimada beddelashadu waa qiyaastii 80%)

● Xagal baladhan oo xagal iyo xagal yar oo socod ah
● Heerkulka ballaaran iyo baaxadda muuqaalka
● Dhaqdhaqaaqa kulaylka sare (2 jeer ka badan BNN crystal)
● Qoyaanka xorta ah
● Isku-dheelid la'aanta ugu yar
● Oogada indhaha oo aad u dhalaalaysa
● Ma jiro qudhun ka hooseeya 900°C
● Makaan ahaan deggan
● Qiimaha jaban marka la barbar dhigo BBO iyo LBO
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
Beddelka Joogtada ah
KTP waxaa markii ugu horreysay loo soo bandhigay sidii kristanta NLO ee nidaamyada laysarka ee Nd doped oo leh hufnaan beddelaad sare leh. Xaaladaha qaarkood, waxtarka beddelka ayaa lagu soo warramey 80%, taas oo ka tagaysa kiristaalo kale ee NLO oo aad uga dambeeya.
Dhowaan, iyada oo la horumarinayo diodes laser, KTP waxaa si ballaaran loo isticmaalaa sida aaladaha SHG ee diode lagu shubay Nd:YVO4 nidaamyada laser adag si ay u soo saaraan laser cagaaran, iyo sidoo kale in nidaamka laser ka dhigo mid aad u cufan.
KTP ee OPA, Codsiyada OPO
Marka laga soo tago isticmaalkeeda ballaaran sida aaladda labanlaabida soo noqnoqda ee nidaamyada laser-ka ee Nd-doped ee wax soo saarka Cagaaran / Cas, KTP sidoo kale waa mid ka mid ah kiristaalo ugu muhimsan ee ilaha parametric ee wax soo saarka la taaban karo ee muuqda (600nm) ilaa bartamaha IR (4500nm) iyadoo ay ugu wacan tahay caannimada iloheeda la shubay, aasaaska iyo iswaafajinta labaad ee Nd:YAG ama Nd:YLF lasers.
Mid ka mid ah codsiyada ugu faa'iido badan ayaa ah marxaladda aan muhiimka ahayn ee ku habboon (NCPM) KTP OPO / OPA oo ay ku shubto lasers-ka tunable si loo helo waxtarka beddelka sare. iyo celceliska heerarka awoodda milli-watt ee calaamadaha iyo soo saarista shaqo la'aanta labadaba.
Waxaa soo saaray laser-ka Nd-doped, KTP OPO waxay heshay wax ka badan 66% wax ku oolnimada beddelka ee hoos u-beddelka 1060nm ilaa 2120nm.
Modulators Electro-Optical
KTP crystal waxa loo isticmaali karaa sida modulators electro-optical. Wixii macluumaad dheeraad ah, fadlan la xidhiidh injineeradayada iibka
