Potasiyumu Titanyl Fosifate (KTiOPO4 cyangwa KTP) KTP ni ibikoresho bikoreshwa cyane mugukuba inshuro ebyiri Nd: YAG hamwe nizindi Nd-dope laseri, cyane cyane iyo ubwinshi bwamashanyarazi buri kurwego rwo hasi cyangwa ruciriritse.Kugeza magingo aya, inshuro ziyongereye hamwe n’imbere-cavity zikubye kabiri Nd: laseri ukoresheje KTP zahindutse isoko yo kuvoma ibintu byerekana amarangi agaragara hamwe na Ti: Lazeri ya safiro kimwe niyongera.Ningirakamaro kandi isoko yicyatsi kubushakashatsi bwinshi ninganda zikoreshwa.
KTP nayo ikoreshwa muguhuza interacavity ivanze 0.81µm diode na 1.064µm Nd: YAG laser kugirango itange urumuri rwubururu na interacavity SHG ya Nd: YAG cyangwa Nd: YAP laseri kuri 1.3µm kugirango itange urumuri rutukura.
Usibye ibiranga bidasanzwe bya NLO, KTP ifite kandi ibyiringiro bya EO na dielectric bigereranywa na LiNbO3.Iyi mitungo yunguka ituma KTP igira akamaro kanini kubikoresho bitandukanye bya EO.
Biteganijwe ko KTP izasimbuza LiNbO3 kristu muburyo butandukanye bwo gukoresha moderi ya EO, mugihe izindi nyungu za KTP zahujwe no kuzirikana, nko kwangirika kwinshi, kwaguka kwinshi kwa optique (> 15GHZ), guhagarika ubushyuhe nubukanishi, no gutakaza bike, nibindi .
Ibintu nyamukuru biranga KTP Crystal ：
Conversion Guhindura inshuro nziza (1064nm SHG ihinduka neza ni 80%)
Co Coefficient nini idafite umurongo (inshuro 15 za KDP)
● Umuyoboro mugari hamwe nu rugendo ruto
Temperature Ubushyuhe bwagutse hamwe nubunini bwagutse
Umuyoboro mwinshi w'ubushyuhe (inshuro 2 z'ubwa BNN)
Porogaramu:
Kwikuba inshuro ebyiri (SHG) ya Nd-ikoporora Laser ya Icyatsi / Umutuku Ibisohoka
● Kuvanga inshuro (SFM) ya Nd Laser na Diode Laser kubisohoka mubururu
Sources Inkomoko y'ibipimo (OPG, OPA na OPO) kuri 0.6mm-4.5mm Ibisohoka
Mod Modulatrice yamashanyarazi (EO) Modulator, Guhindura optique, hamwe naba Coupler bayobora
● Optical Waveguides kubikoresho bya NLO hamwe na EO bihujwe a = 6.404Å, b = 10.615Å, c = 12.814Å, Z = 8
