I-KTA Crystal

Incazelo emfushane:

I-KTA (i-Potassium Titanyle Arsenate, KTiOAsO4) ingilazi elingabonakali elangeni elingafani ne-KTP lapho i-athomu P ithathelwa indawo yi-As. Inezakhiwo ezinhle ezingekho emgqeni we-optical ne-electro-optical, isb ukunciphisa kakhulu ukumuncwa ebangeni lebhande le-2.0-5.0 broadm, okubanzi kwe-angular and lokushisa band, ama-dielectric aphansi.

Amathegi Omkhiqizo

I-KTA (Potassium Titanyle Arsenate, KTiOAsO4 ) iyi-crystal engabonakali ye -lineline efana ne-KTP lapho i-athomu P ithathelwa indawo yi-As. Inezakhiwo ezinhle ezingekho emgqeni we-optical ne-electro-optical, isb ukunciphisa kakhulu ukumuncwa ebangeni lebhande le-2.0-5.0 broadm, okubanzi kwe-angular and lokushisa band, ama-dielectric aphansi.

Uma kuqhathaniswa ne-KTP, izinzuzo eziphambili ze-KTA zifaka phakathi: ukuphakama kwe-oda lesibili kwe-nonlinear, i-IR wave-off wavelength ende, kanye nokufakwa kancane ku-3.5 µm. I-Kta futhi inokusebenza okuphansi kwe-ionic kunalokho kwe-KTP, okuphumela ekunciphiseni umngcele wokulimala we-laser.

I-KTA isetshenziselwa kakhulu isicelo se-Optical Parametric Oscillation (OPO) esinika amandla amaningi okuguqula amandla (ngaphezulu kwe-50%) yemisebe ye-laser ethandekayo kuma-lasers aqinile.

Xhumana nathi ngesixazululo esihle kakhulu sohlelo lwakho lokusebenzisa amakristalu we-KTA.

Izinzuzo ze-WISOPTIC - KTA

• I-homogeneity ephezulu, ikhwalithi yangaphakathi enhle

• Ikhwalithi ephezulu yokuphamba komhlaba

• Ibhulokhi enkulu ngosayizi ohlukahlukene (isib. 10x10x30mm3, 5x5x35mm3)

• I-coeffense enkulu enkulu engafani nolayini, ukuguqulelwa okuphezulu

• Ububanzi bokukhanya obubanzi, ububanzi bokuqhathanisa okushisa obukhulu
