KTP Crystal
KTP (KTiOPO4 ) yog ib qho ntawm cov khoom siv feem ntau siv cov khoom siv kho qhov muag tsis muag khoom. Piv txwv li, nws nquag siv rau zaus ntau zaus ntawm Nd: YAG lasers thiab lwm yam Nd-doped lasers, tshwj xeeb tshaj yog nyob rau qis lossis nruab nrab-zog ceev. KTP tseem siv dav li OPO, EOM, cov khoom siv kho qhov muag yoj-qhia, thiab hauv cov khoom coj hauv kev coj ua ke.
KTP nthuav tawm lub teeb pom kev zoo tshaj plaws, qhov pom dav dav, dav dav pom zoo, lub kaum kev taug kev me me, thiab hom I thiab II tsis tseem ceeb theem sib txuam (NCPM) nyob rau hauv qhov sib txawv. KTP tseem muaj qhov kawg ua haujlwm siab SHG coefficient (kwv yees 3 zaug siab dua li ntawm KDP) thiab qhov ntsuas qhov siab raug qhov tsis zoo (> 500 MW / cm²).
Cov neeg tsis tu ncua nyob rau KTP muaj kev nyuaj siab los ntawm qhov tsaus thiab ua kom tawg ("grey-track") thaum siv thaum lub sijhawm SHG cov txheej txheem ntawm 1064 nm ntawm qhov nruab nrab lub zog nruab nrab thiab qhov rov ua dua tus nqi siab dua 1 kHz. Rau siab nruab nrab-siv hluav taws xob, WISOPTIC muaj siab grey track resistance (HGTR) KTP muaju cog los ntawm cov txheej txheem hydrothermal. Cov muaju hauv nruab nrog muaj qhov qis IR thawj zaug kev nqus thiab tsawg cuam tshuam los ntawm lub teeb ntsuab dua li ib txwm KTP, yog li zam cov teeb meem ntawm teeb meem tsis haum lub hwj chim tsis haum, kev ua kom poob qis, siv lead ua tsaus, thiab cov teeb tsa los cuam tshuam.
Raws li ib qho ntawm cov KTP qhov tseem ceeb hauv cov khoom lag luam thoob ntiaj teb, WISOPTIC muaj cov peev txheej siab ntawm cov khoom xaiv, kev ua (polishing, txheej), ntau ntau lawm, kev xa khoom sai thiab lub sijhawm lav zoo ntawm KTP zoo. Nws kuj tsim nyog hais tias peb tus nqi yog tus nqi tsim nyog heev.
Tiv tauj peb rau qhov kev daws teeb meem zoo tshaj plaws rau koj daim ntawv thov KTP muaju.
