ICrystal KTP
I-KTP (KTiOPO4 ) yenye yezona zixhobo ziqhelekileyo ezisetyenziswayo ezingasetyenziswayo. Umzekelo, isetyenziswa rhoqo ukuphindaphinda kabini kwe-Nd: I-laser ye-las kunye nezinye ii-las-doped lasers, ngakumbi kwindawo ekumgangatho ophantsi okanye ophakathi. I-KTP isetyenziswa ngokubanzi njenge-OPO, i-EOM, isixhobo sokukhokela amaza ombane, kunye nokulandela isibini.
I-KTP ibonisa ubungakanani obuphezulu bokukhanya, uluhlu olubanzi lokubonisa, i-angle yokwamkelwa ebanzi, i-angle yokuhamba encinci yokuhamba, kunye nohlobo I kunye ne-II engalunganga yokulinganisa isigaba (i-NCPM) kuluhlu olubanzi lwamandla. I-KTP ikwanokulingana okuphezulu okusebenzayo kwe-SHG (malunga namaxesha ama-3 ukuphakama kunaleyo ye-KDP) kwaye umqobo omkhulu womonakalo obonakalayo (> 500 MW / cm²).
Iikristali ezihlala zikhula rhoqo ze-KTP zibakho ngenxa yokufiphala kunye nokusebenza ngokukuko ("grey-track") xa isetyenziswe ngexesha lenkqubo ye-SHG ye-1064 nm kumgangatho ophakathi wamanqanaba kunye namanqanaba okuphindaphinda ngaphezulu kwe-1 kHz. Kwizicelo zamandla aphakamileyo aphezulu, i-WISOPTIC ibonelela ngomgangatho ophezulu wokumelana nengwevu (HGTR) amakristali e-KTP akhule ngendlela ye-hydrothermal. Iikristali ezinjalo zinokufakwa okuncinci kwe-IR kwaye azichatshazelwa kukukhanya okuluhlaza kune-KTP eqhelekileyo, ngoko ke zithintele iingxaki zokufakelwa kwamandla ombane, ukuhla kokusebenza, ukumnyama kwekristale, kunye nokugqobhoza komthi.
Njengomnye wabanikezeli abaphambili bemithombo ye-KTP kwimarike yamanye amazwe, i-WISOPTIC inamandla aphakamileyo okhetho lwezinto, ukuqhubekeka (ukuloba, ukuloba), ukuvelisa ngobuninzi, ukuhanjiswa okukhawulezayo kunye nexesha elide lokuqinisekiswa komgangatho we-KTP. Kukwakufanelekile ukuba sikhankanye ukuba ixabiso lethu lisengqiqweni.
Nxibelelana nathi ngesona sisombululo silungileyo kwisicelo sakho seekristali ze-KTP.
