LBO Crystal
LBO (LiB3O5) ndi mtundu wa makristalu osayimira mzere wowoneka bwino wopatsirana moyenera (210-2300 nm), cholowera kwambiri cha laser komanso njira yayikulu yogwiritsira ntchito pafupipafupi (pafupifupi 3 nthawi ya kristalo ya KDP). Chifukwa chake LBO imagwiritsidwa ntchito popanga magetsi apamwamba achiwiri komanso achitatu a harmon laser, makamaka ma laser a ultraviolet.
LBO ili ndi dera lalikulu la band ndi chiwonetsero chachikulu, kuphatikiza kwakukulu kosagwirizana, zida zabwino zamapangidwe ndi makina. Izi zimapangitsa kuti kristalo uyu akhale wokhoza kuwunika kwa ma parametric process (OPO / OPA) komanso noncritical phase match (NCPM), nawonso.
Lumikizanani nafe kuti mupeze yankho lanu labwino kwambiri la makhiristo a LBO.
Luso la WISOPTIC -LBO
• Kubzala kwakukulu: max 20x20 mm
• Zosiyanasiyana: kutalika kwakulu 60 mm
• Mapeto: kumapeto, kapena Brewster, kapena kutchulidwa
• Ma transmittance apamwamba: AR yophimba ndi R <0.1% (pa 1064 / 532nm)
• Kukwera: pempho
• Mtengo wopikisana kwambiri

Zofunikira - LBO
• Mawonekedwe owonekera kuchokera ku 160 nm mpaka 2.6 µm
• Maso apamwamba a homogeneity, opanda kuphatikiza
• Zogwirizana bwino kwambiri za SHG (pafupifupi katatu nthawi ya KDP)
• Mitundu yotakata yotulutsa mtundu wa Type I ndi Type II yosafunikira kwenikweni (NCPM)
• Makulidwe ovomerezeka, oyenda pang'ono
• Pazowonongeka zapamwamba za laser
Kuyerekeza kuchuluka kwa zowononga zambiri [1064nm, 1.3ns]
