I-KTP Crystal
I-KTP (KTiOPO4 ) ingenye yezinto ezisetshenziswa kakhulu ezisetshenziswayo ze-nonlinear optical. Isibonelo, isetshenziselwa njalo ukuphindwaphindwa kwe-Nd: YAG lasers nezinye i-Nd-doped lasers, ikakhulukazi ezindaweni eziphansi noma eziphakathi. I-KTP futhi isetshenziswa kabanzi njenge-OPO, i-EOM, izinto eziholwa ngumhlahlandlela we-optical, kanye nakuma-coupers aqondile.
I-KTP ikhombisa ikhwalithi ephezulu yokukhanya, ibanga lokubonisa ebanzi, i-angle eyamukelayo ebanzi, i-angle encane yokuhamba, futhi uthayiphe i-I ne II-non-esibucayi yokuqhathanisa isigaba (i-NCPM) ebangeni le-wave waveth wide. I-KTP futhi inokulingana okuphelele okusebenzayo kwe-SHG (cishe izikhathi ezi-3 eziphakeme kunalokho kwe-KDP) nomkhawulo wokulimala okuphezulu (1 500 MW / cm²).
Amakristalu ejwayelekile akhula nge-flux akhuliswa i-flux ngenxa yokufiphala nokusebenza kahle ("grey-track") lapho isetshenziswa phakathi nenqubo ye-SHG ye-1064 nm ngamazinga wamandla aphezulu namazinga wokuphindaphinda ngaphezulu kwe-1 kHz. Ngezicelo eziphezulu zamandla aphezulu, i-WISOPTIC inikezela ngamanani aphezulu we-track grey (HGTR) amakristalu we-KTP akhule ngendlela ye-hydrothermal. Amakristalu anjalo anokufakwa okuncane kwe-IR okuqala futhi athinteka kancane ngokukhanya okuluhlaza kune-KTP ejwayelekile, ngaleyo ndlela ugweme izinkinga zokuxhuma kwamandla we-harmonic, ukwehla kokusebenza kahle, ukumelana nokukhanya kwe-crystal, nokuhlanekezela ugongolo.
Njengomunye wabahlinzeki abakhulu bomthombo we-KTP kuyo yonke imakethe yamazwe omhlaba, i-WISOPTIC inamandla aphezulu wokukhethwa kwezinto ezibonakalayo, ukucubungula (ukupolisha, ukugoqa), ukukhiqizwa ngobuningi, ukulethwa okusheshayo nesikhathi eside sekhwalithi yekhwalithi ye-KTP. Kubalulekile futhi ukusho ukuthi intengo yethu inengqondo impela.
Xhumana nathi ukuthola isixazululo esihle kakhulu sohlelo lwakho lokusebenzisa amakristalu we-KTP.
