KDP & DKDP Crystal
KDP (KH2KHOTSO4 ) le DKDP / KD * P (KD2KHOTSO4 ) ke tse ling tsa thepa e sebelisoang haholo khoebong ea NLO. Ka phetiso e ntle ea UV, sebaka se senyehileng sa tšenyo e ngata, le birefringence e phahameng, thepa ena e sebelisoa hangata bakeng sa ho pheta-pheta makhetlo a mararo ha Nd: YAG laser.
Ka lisebelisoa tse phahameng tsa EO, likristale tsa KDP le DKDP li boetse li sebelisoa haholo ho etsa lisele tsa Pockels bakeng sa sisteme ea laser, joalo ka Nd: YAG, Nd: YLF, Ti-Sapphire, Alexandrite, jj. KDP le DKDP ka bobeli li ka etsa karolo e lekanang ea mofuta oa I le thaepa II bakeng sa SHG le THG ea 1064nm Nd: YAG laser. Re khothaletsa KDP bakeng sa FGH ea Nd: YAG laser (266nm).
Joaloka e 'ngoe ea barekisi ba kholo ba KDP / DKDP (moetsi oa mohloli)' marakeng ohle oa machabeng, WISOPTIC e na le bokhoni bo phahameng ba khetho ea thepa, ts'ebetso (polishing, coating, plating ea khauta, jj.). WISOPTIC e tiisa theko e nepahetseng, tlhahiso ea bongata, ho tlisa kapele le nako e telele ea tiiso ea lisebelisoa tsena.
Ikopanye le rona bakeng sa tharollo e nepahetseng bakeng sa ts'ebeliso ea hau ea likhalase tsa KDP / DKDP.
