Crystal Kta

Kufotokozera Mwachidule:

KTA (Potaziyamu Titanyle Arsenate, KTiOAsO4) ndi galasi loyang'ana ngati mzere wofanana ndi KTP momwe atomu P yasinthidwa 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.

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
