Nd: Crystal wa YAG
Nd: YAG (Neodimium Doped Yttrium Aluminium Garnet) yakhala ndipo ikupitirirabe kukhala galasi logwiritsa ntchito kwambiri laser kwa laser olimba boma. Moyo wabwino wa fluorescence nthawi zambiri (kuposa kawiri kuposa Nd: YVO)4) komanso makondedwe ochulukitsa, komanso chikhalidwe chowoneka bwino, chimapangitsa Nd: YAG galasi ikhale yoyenera kwambiri pamafunde osasunthika, mafunde apamwamba a Q-swit single and single mode.
WISOPTIC imapereka Nd: YAG imakhala ndi zinthu zotsatirazi: milingo yosiyanasiyana yodumphadumpha, kuwala kwapamwamba kozungulira, kulondola kwambiri, kulondola bwino mbiya komanso mbali ya wedge, kudula kosiyanasiyana, zokutira kosiyanasiyana kosiyanasiyana.
Lumikizanani nafe kuti muthane ndi mayankho abwino a momwe mungagwiritsire ntchito Nd: YAG makhristali.
Luso la WISOPTIC - Nd: YAG
• Mitundu yosiyanasiyana ya Nd-doping ratio (0.1% ~ 1.3at%)
• Mitundu yosiyanasiyana ya ndodo kapena ma slabs (lathyathyathya, omata, Brewster, okonzedwa, ndi zina)
• Maso apamwamba kwambiri
• Kuchita zolondola kwambiri
• Kuthira kwamtundu wapamwamba, choponderezedwa kwambiri
• Mtengo wopikisana kwambiri, kutumiza mwachangu

Zofunikira Kwambiri - Nd: YAG
• Kupeza kwambiri, kutsika pang'ono, kugwira ntchito kwambiri
• Kugawa Kwambiri kwa Nd ndikuwonetsetsa bwino
• Mkulu matenthedwe wazitsulo, mkulu matenthedwe kukana
• Homogeneity yayikulu, kusunthika kotsika
• Kuwona bwino kwambiri, kutayika kotsika kamodzi (makamaka pa 1064nm)
• Mitundu yosiyanasiyana yogwira (CW, pulsed, Q-switch, mode Lock)
