KTP - Kwikuba kabiri kwa Nd: yag Laser Nizindi Nd-Dop Laser
Ibisobanuro ku bicuruzwa
KTP nibikoresho bikoreshwa cyane muburyo bwo gukuba inshuro ebyiri Nd: YAG laseri nizindi Nd-dope laseri, cyane cyane mubucucike buke cyangwa buciriritse.
Ibyiza
Conversion Guhindura inshuro nziza (1064nm SHG ihinduka neza ni 80%)
Co Coefficient nini idafite umurongo (inshuro 15 za KDP)
● Umuyoboro mugari hamwe nu rugendo ruto
Temperature Ubushyuhe bwagutse hamwe nubunini bwagutse
Umuyoboro mwinshi w'ubushyuhe (inshuro 2 z'ubwa BNN)
Ubushuhe
● Ntarengwa idahuye
Surface Ubuso bwiza cyane
● Nta kubora munsi ya 900 ° C.
● Muburyo butajegajega
Cost Igiciro gito ugereranije na BBO na LBO
Porogaramu
Kwikuba inshuro ebyiri (SHG) ya Nd-ikoporora Laser ya Icyatsi / Umutuku Ibisohoka
● Kuvanga inshuro (SFM) ya Nd Laser na Diode Laser kubisohoka mubururu
Sources Inkomoko y'ibipimo (OPG, OPA na OPO) kuri 0,6mm-4.5mm Ibisohoka
Mod Modulatrice yamashanyarazi (EO) Modulator, Guhindura optique, hamwe naba Coupler bayobora
● Optical Waveguides kubikoresho bya NLO hamwe na EO
Guhindura inshuro
KTP yatangijwe bwa mbere nka NLO kristu ya Nd doped laser sisitemu ifite ubushobozi bwo guhindura byinshi. Mubihe bimwe na bimwe, imikorere yo guhinduka yavuzwe kuri 80%, igasiga izindi kirisiti ya NLO inyuma cyane.
Vuba aha, hamwe niterambere rya diode ya laser, KTP ikoreshwa cyane nkibikoresho bya SHG muri diode yavomye Nd: YVO4 sisitemu ikomeye ya laser kugirango isohore icyatsi kibisi, kandi no gukora sisitemu ya laser.
KTP Kuri OPA, Porogaramu ya OPO
Usibye gukoreshwa kwinshi nkigikoresho cyikubye inshuro ebyiri muri sisitemu ya Nd-ikoporora laser ya Green / Umutuku, KTP nayo nimwe mubintu byingenzi bya kristaliste mubisobanuro byatanzwe kugirango bishoboke gusohoka kuva bigaragara (600nm) kugeza hagati ya IR (4500nm) kubera gukundwa kwamasoko yavomwe, ibyingenzi nubwa kabiri bihuza Nd: YAG cyangwa Nd: YLF laseri.
Imwe muma progaramu yingirakamaro cyane ni icyiciro kidahuye nicyiciro (NCPM) KTP OPO / OPA yavomwe na lazeri ihindagurika kugirango ibone uburyo bwiza bwo guhinduka.KTP OPO itanga ibisubizo bihoraho bikomeza bya femto-isegonda ya 108 Hz yo gusubiramo na milli-watt impuzandengo yimbaraga murwego rwibimenyetso nibisohoka.
Kuvomwa na Nd-dope laseri, KTP OPO yabonye hejuru ya 66% yo guhindura imikorere yo kumanuka kuva 1060nm ikagera kuri 2120nm.
Abayobora amashanyarazi
KTP kristal irashobora gukoreshwa nka moderi ya electro-optique. Kubindi bisobanuro, nyamuneka hamagara abashinzwe kugurisha.
