KDP & DKDP Crystal

Cov lus piav qhia luv luv:

KDP (KH2PO4) thiab DKDP / KD * P (KD2PO4) yog cov khoom lag luam tshaj plaws hauv NLO. Nrog rau kev sib kis zoo UV, kev tiv thaiv kev puas tsuaj loj, thiab lub siab birefringence, cov khoom siv no feem ntau yog siv rau ob npaug, peb npaug thiab plaub npaug ntawm Nd: YAG laser.

Cov khoom lag luam

KDP (KH2PO) thiab DKDP / KD * P (KD2PO) yog ntawm cov khoom siv dav dav hauv NLO. Nrog rau kev sib kis zoo UV, kev tiv thaiv kev puas tsuaj loj, thiab lub siab birefringence, cov khoom siv no feem ntau yog siv rau ob npaug, peb npaug thiab plaub npaug ntawm Nd: YAG laser.

Nrog siab EO coefficient, KDP thiab DKDP muaju tseem siv dav los ua Pockels hlwb rau laser system, xws li Nd: YAG, Nd: YLF, Ti-Sapphire, Alexandrite, thiab lwm yam. Txawm hais tias DKDP nrog siab deuteration feem ntau siv, KDP thiab DKDP ob leeg tuaj yeem ua ntu sib txuam ntawm hom I thiab hom II rau SHG thiab THG ntawm 1064nm Nd: YAG laser. Peb pom zoo KDP rau FGH ntawm Nd: YAG laser (266nm).

Raws li ib qho ntawm KDP / DKDP cov khoom xa khoom loj (qhov chaw tsim khoom) hauv kev lag luam thoob ntiaj teb, WISOPTIC muaj peev xwm ntau ntawm cov khoom siv xaiv, kev ua (polishing, txheej, kub-plating, thiab lwm yam). WISOPTIC lees tias tus nqi tsim nyog, tsim ntau lawm, xa khoom ceev thiab lub sijhawm lav ntev ntawm cov khoom siv no.

Tiv tauj peb rau qhov kev daws teeb meem zoo tshaj plaws rau koj daim ntawv thov KDP / DKDP muaju.
