Kta Crystal
KTA (Potasiamu Titanyle Arsenate, KTiOAsO)4 ) is nonlinear optical crystal yakafanana neKTP umo atomu P inotsiviwa naA. Iyo ine yakanaka isiri-mutsara wekutarisa uye yemagetsi-e-maziso, svikiro yakaderedzwa kupinda mukati mebhendi ye1.0-5.0 µm, yakafara angular uye tembiricha bandwidth, yakaderera dielectric constants.
Kuenzaniswa neKTP, izvo zvakanyanya kukosha zveKTA zvinosanganisira: yakakwirira yechipiri-kurongeka nonlinear coefficient, yakareba IR yakatemwa-kuregedzwa kwemhepo, uye kushomeka kushomeka pa3,5 µm. Kta zvakare ine yakadzika ionic conductor kupfuura iyo yeKTP, iyo inoguma yakakwira laser inosimudzira kukuvadza pasi.
Kta inonyanya kuzivikanwa inoshandiswa kweOpical Parametric Oscillation (OPO) application iyo inopa yakanyanya simba simba kutendeuka mashandiro (pamusoro 50%) ye tunable laser radiation mune yakasimba lasers.
Bata isu kune mhinduro yakanakisa yekushandisa kwako makristasi eKTA.
WISOPTIC Kubatsira - KTA
• Yakakwira homogeneity, yakanaka yemukati yemhando
• yepamusoro yepamusoro yekupukuta kwepasi
• Chikamu chikuru chehukuru hwakasiyana (semuenzaniso 10x10x30mm3, 5x5x35mm3)
• Yakakura isingaenzaniswi coefficient, yakakwirira shanduko kushanda
• Broad pachena pachena nzvimbo, yakakura tembiricha yakaenzana upamhi
• AR machira ekutenderera mafungu kubva kubva pamwenje unooneka kusvika 3300 nm
• Yakanyanya kukwikwidzana mutengo, kukurumidza kutumira
