Crystal Kta
KTA (Potaziyamu Titanyle Arsenate, KTiOAsO4 ) ndi galasi loyang'ana ngati nonlinear lofanana ndi KTP momwe atomu P imasinthidwa ndi As. Ili ndi katundu wosagwirizana ndi ma waya komanso ma electro-Optical, mwachitsanzo, kuchepetsedwa kwa mayankho mu gulu la 2.0-5.0 µm, wide angular ndi kutentha bandwidth, ochepa ma dielectric constants.
Poyerekeza ndi KTP, zabwino zazikulu za KTA ndizophatikiza: kuphatikiza kwachiwiri kopanda dongosolo lamtundu wamtundu, kutalika kwa ma IR osadukiza, komanso kuyamwa pang'ono pa 3.5 µm. KTA ilinso ndi ma ionic conductor ocheperako kuposa a KTP, omwe amachititsa kuti laser yapamwamba ikuluze zowonongeka.
KTA imagwiritsidwa ntchito kwambiri pa ntchito ya Optical Parametric Oscillation (OPO) yomwe imapatsa mphamvu kwambiri kutembenuka kwamphamvu (pamwamba pa 50%) ya radiation yotupa ya laser mu lasers yolimba.
Lumikizanani nafe kuti mupeze yankho lanu labwino kwambiri la makristalo a KTA.
Ubwino WISOPTIC - KTA
• High homogeneity, yabwino kwambiri yamkati
• Zapamwamba kwambiri pakupukuta kwapamwamba
• Chipika chachikulu cha kukula kosiyanasiyana (mwachitsanzo 10x10x30mm3, 5x5x35mm3)
• Kukwanira kwakukulu kopanda mawonekedwe, kusintha kwakukulu
• Malo owonekera pang'onopang'ono, m'lifupi mwake;
• Zovala za AR za mawayilesi kuchokera pa kuwala kowonekera mpaka 3300 nm
• Mtengo wopikisana kwambiri, kutumiza mwachangu

Mfundo Zazikulu - KTA
• Kutentha kokwanira kwambiri kosagwirizana, magetsi okwanira pama Electro
• Makulidwe ovomerezeka, mbali yaying'ono
• Malo owonekera pang'onopang'ono, m'lifupi mwake;
• Ma dielectric ang'onoang'ono osasunthika, otsika a ionic
• Kunyamula kotsika mu mawonekedwe a chiwonetsero cha 3-4 µm kuposa a KTP
• Pazowonongeka zapamwamba za laser
Mapulogalamu Oyambirira - KTA
• OPO ya m'ma IR m'badwo - mpaka 4 µm
• Sum ndi Kusiyana Frequency Generation m'ma IR magawo
• Electro-Optical modulation ndi Q-switching
• Kuchita mobwerezabwereza (SHG @ 1083nm-3789nm).
