LBO Crystal

LBO. .
LBO ni icyiciro gihuza SHG na THG ya Nd: YAG na Nd: YLF laseri, ukoresheje ubwoko bwa I cyangwa ubwoko bwa II imikoranire.Kuri SHG ku bushyuhe bwicyumba, andika icyiciro cya I guhuza birashobora kugerwaho kandi bifite coeffisente nziza ya SHG mu ndege nyamukuru ya XY na XZ mu burebure bwagutse kuva kuri 551nm kugeza kuri 2600nm.SHG ihindura imikorere irenga 70% kuri pulse na 30% kuri cw Nd: YAG laseri, hamwe na THG ihindura hejuru ya 60% kuri pulse Nd: laser ya YAG byagaragaye.
LBO ni kristu nziza ya NLO kuri OPOs na OPAs hamwe nuburebure bwumurongo muremure hamwe nimbaraga nyinshi.Izi OPO na OPA zapompe na SHG na THG za Nd: YAG laser na XeCl excimer laser kuri 308nm byavuzwe.Imiterere yihariye yubwoko bwa I nubwoko bwa II icyiciro kimwe kimwe na NCPM gisiga icyumba kinini mubushakashatsi no gushyira mu bikorwa OPO na OPA ya LBO.
Ibyiza:
• Gukorera mu mucyo kuva kuri 160nm kugeza kuri 2600nm;
• Ubwinshi bwa optique homogeneity (δn≈10-6 / cm) no kutabamo;
• Ugereranije nini ya SHG ikora neza (hafi inshuro eshatu za KDP);
• Umubare wangiritse cyane;
• Inguni yo kwakirwa yagutse no kugenda-kugenda;
• Andika I na Ubwoko bwa II butari icyiciro gihuza (NCPM) murwego rugari;
• NCPM ya Spectral hafi 1300nm.
Porogaramu:
• Ibisohoka birenga 480mW kuri 395nm bitangwa numurongo wikubye kabiri 2W uburyo bufunze Ti: Lazeri ya safiro (<2ps, 82MHz).Uburebure bwumurambararo wa 700-900nm butwikiriwe na kristu ya 5x3x8mm3 LBO.
• Icyatsi kirenga 80W kiboneka na SHG ya Q yahinduwe Nd: YAG laser muburyo bwa II 18mm z'uburebure bwa LBO.
• Inshuro zikubye kabiri ya diode yavomye Nd: YLF laser (> 500μJ @ 1047nm, <7ns, 0-10KHz) igera kuri 40% yo guhindura imikorere muri 9mm z'uburebure bwa LBO.
• VUV isohoka kuri 187.7 nm iboneka kubisekuruza-inshuro nyinshi.
• 2mJ / pulse itandukanya-igabanya urumuri kuri 355nm iboneka hamwe ninshuro zidasanzwe zikuba inshuro eshatu Q yahinduwe Nd: YAG laser.
• Ihinduka ryinshi cyane muri rusange hamwe na 540-1030nm iringaniye yumurambararo wabonetse hamwe na OPO yavomwe kuri 355nm.
• Ubwoko bwa I OPA bwapompe kuri 355nm hamwe na pompe-to-signal imbaraga zo guhindura ingufu za 30% byavuzwe.
• Ubwoko bwa II NCPM OPO yavomwe na XeCl excimer laser kuri 308nm imaze kugera kuri 16.5% muburyo bwo guhindura, kandi intera ndende iringaniye irashobora kuboneka hamwe nisoko itandukanye yo kuvoma no guhuza ubushyuhe.
• Ukoresheje tekinike ya NCPM, andika I OPA yavomwe na SHG ya Nd: laser ya YAG kuri 532nm nayo yagaragaye kugirango igere ku ntera yagutse kuva kuri 750nm kugeza 1800nm ​​ukoresheje ubushyuhe buva kuri 106.5 ℃ kugeza 148.5 ℃.
• Ukoresheje ubwoko bwa II NCPM LBO nka generator optique (OPG) hamwe nubwoko bwa I bukomeye icyiciro cyahujwe na BBO nka OPA, umurongo muto (0.15nm) hamwe na pompe-to-signal yerekana imbaraga (32.7%) byabonetse iyo ivomwe na 4.8mJ, 30ps laser kuri 354.7nm.Umuhengeri wo guhuza umurongo uva kuri 482.6nm ukagera kuri 415.9nm washyizweho haba mukongera ubushyuhe bwa LBO cyangwa mukuzenguruka BBO.
