Uguqulo lwamaxesha amaninzi
I-KTP yaziswa okokuqala njengekristale ye-NLO yeenkqubo ze-laser ze-Nd ezinokuguqulwa okuphezulu. Ngaphantsi kweemeko ezithile, ukusebenza kakuhle kokuguqulwa kwabikwa kwi-80%, eshiya ezinye iikristale ze-NLO ezikude.
Kutshanje, ngophuhliso lwe-laser diode, i-KTP isetyenziswa ngokubanzi njengezixhobo ze-SHG kwi-diode impompo ye-Nd: YVO4 iinkqubo ze-laser eziqinileyo zokuvelisa i-laser eluhlaza, kunye nokwenza inkqubo ye-laser icwecwe kakhulu.
KTP Ye OPA, OPO Izicelo
Ukongeza kusetyenziso lwayo olubanzi njengesixhobo esiphindwe kabini kwiinkqubo ze-laser ye-Nd-doped yemveliso eluhlaza/eBomvu, i-KTP ikwayenye yezona kristale zibalulekileyo kwimithombo yeparametric yemveliso enokutyinwa ukusuka kokubonakalayo (600nm) ukuya kumbindi-IR (4500nm) ngenxa yokuthandwa kwemithombo yayo empompo, i-harmonic esisiseko kunye neyesibini ye-Nd: YAG okanye i-Nd: YLF lasers.
Esinye sezicelo eziluncedo kakhulu yi-non-critical phase-matched (NCPM) i-KTP OPO/OPA empontshwe yi-laser e-tunwable ukufumana ukuguqulwa okuphezulu. I-KTP ye-OPO iphumela kwiziphumo eziqhubekayo ezizinzileyo ze-femto-yesibini i-pulse ye-108 Hz yokuphindaphinda izinga. kunye ne-milli-watt i-avareji yomgangatho wamandla kuzo zombini iisignali kunye neziphumo ezingasebenziyo.
I-Pumped by lasers Nd-doped, i-KTP i-OPO ifumene ngaphezulu kwe-66% yokuguqulwa kwempumelelo yokuguqulwa kwe-down-conversion ukusuka kwi-1060nm ukuya kwi-2120nm.
IiModyuli ze-Electro-Optical
Ikristale ye-KTP ingasetyenziswa njengeemodyuli ze-electro-optical. Ngolwazi oluthe vetshe, nceda uqhagamshelane neenjineli zethu zentengiso.
