KTP Crystal
KTP (KTiOPO4 ) jẹ ọkan ninu awọn ohun elo opitan ti kii ṣe deede ti a lo julọ. Fun apẹẹrẹ, o lo igbagbogbo fun ilọpo meji ti Nd: awọn aṣiṣẹ YAG ati awọn lasers Nd-doped miiran, pataki ni iwuwo kekere tabi alabọde. A tun lo KTP ni lilo pupọ bi OPO, EOM, ohun elo itọsọna igbi-opiti, ati ni awọn ọna itọsọna.
KTP ṣafihan didara gaju ti o gaju, sakanianiyeyeyeyeyeyeyeyeyeyeyeyeyeyeyeyeyeye, igun itẹwọgba jakejado, igun kekere ti o nrin, ati iru I ati II ti ibaamu ipele-ipele aiṣe-pataki (NCPM) ni sakani igbohunsafẹfẹ jakejado. KTP tun ni atọwọdọwọ SHG munadoko to gaju (nipa awọn akoko 3 ti o ga ju ti KDP lọ) ati ilo opin ibajẹ eeyan gaju (> 500 MW / cm²).
Awọn kirisita KTP ṣiṣan igbagbogbo lo jiya lati didamu ati fifọ ṣiṣe ("grẹy-orin") nigba lilo lakoko ilana SHG ti 1064 nm ni awọn ipele agbara agbara giga ati awọn oṣuwọn atunwi loke 1 kHz. Fun awọn ohun elo agbara-agbara giga, WISOPTIC nfunni ni igbẹkẹle orin gbigbo giga (HGTR) kirisita KTP ti o dagba nipasẹ ọna hydrothermal. Iru awọn kirisita wọnyi ni gbigba gbigba kekere akọkọ ti IR ati pe o kere si ni ipa nipasẹ ina alawọ ewe ju KTP deede, nitorinaa yago fun awọn iṣoro ti awọn agbara agbara isunku, awọn ifunra ṣiṣe ṣiṣe, didan dudu, ati iparun tan ina.
Gẹgẹbi ọkan ninu awọn olupese orisun orisun KTP ni gbogbo ọja okeere, WISOPTIC ni agbara giga ti yiyan ohun elo, ṣiṣe (didi, iṣupọ), iṣelọpọ ibi, ifijiṣẹ iyara ati akoko iṣeduro gigun ti KTP didara. O tun tọ lati darukọ pe iye wa jẹ ironu tootọ.
