Nd: YAG Crystal
Nd: Ua lilo ʻo YAG (Neodimium Doped Yttrium Aluminum Garnet) i lilo a me ka hoʻomehana mau i ka nui o ka mīkini i hoʻohana ʻia no ka laser mea ikaika. ʻO nā haʻalulu maikaʻi maikaʻi e pono ai (ʻelua mau manawa ma mua o Nd: YVO4) a me ka thermal conductivity, me ka ʻano kūlohelohe, hana ʻo Nd: YAG crystal i kūpono no ka kahe ka nui o ka hoʻokele kala ʻana, ka nui o ka ikaika Q-hoʻololi a me nā hana mode hoʻokahi.
Hāʻawi ʻo WISOPTIC i ka lāʻau pā Nd: YAG me nā hiʻohiʻona: ka pae doping kiʻekiʻe, kiʻekiʻe homogeneity kiʻekiʻe, kūkaʻi nui ka hoʻōla ʻana, pololei ka ʻalohilohi ʻana a me nā kihi, ʻoi aku nā hopena hope, nā pālule dielectric like ʻole, ka paepae poino kiʻekiʻe.
E kāhea iā mākou no ka hoʻonā maikaʻi loa no kāu noi o Nd: YAG crystals.
ʻĀina WISOPTIC - Nd: YAG
• nā koho ʻē aʻe o ka pā ʻana o Nd-doping ratio (0.1% ~ 1.3at%)
• Nā koho like ʻole o ka lāʻau aiʻa a i ʻole maʻa (ʻāpana, mare, Brewster, grooved, etc.)
• He homogeneity optical kiʻekiʻe
• Ka ʻike kiko piha
• Kaikoʻi maikaʻi maikaʻi loa, ka paepae pōʻino kiʻekiʻe
• He kumukūʻai paʻakikī, lawe wikiwiki
