Yb: YAG–1030 Nm Laser Crystal Promising Laser-active Material
Mafotokozedwe Akatundu
Yb:YAG crystal ikuyembekezeka kulowa m'malo mwa Nd:YAG kristalo pamagetsi opopa amphamvu kwambiri a diode ndi ntchito zina zomwe zingatheke.
Yb:YAG ikuwonetsa lonjezo lalikulu ngati chida champhamvu cha laser.Mapulogalamu angapo akupangidwa m'munda wa lasers mafakitale, monga kudula zitsulo ndi kuwotcherera.Ndi Yb:YAG yapamwamba kwambiri yomwe ilipo tsopano, magawo owonjezera ndi mapulogalamu akufufuzidwa.
Ubwino Wa Yb:YAG Crystal
● Kutentha kochepa kwambiri, kosakwana 11%
● Kuthamanga kwambiri kwa malo otsetsereka
● Mayamwidwe okulirapo, pafupifupi 8nm@940nm
● Palibe mayamwidwe osangalatsa kapena kutembenuka
● Amapopedwa mosavuta ndi ma diode a InGaAs odalirika pa 940nm (kapena 970nm)
● High matenthedwe madutsidwe ndi lalikulu mawotchi mphamvu
● Mawonekedwe apamwamba kwambiri
Mapulogalamu
Yokhala ndi bandi yapampu yotakata komanso gawo labwino kwambiri lotulutsa Yb:YAG ndi galasi loyenera kupopera diode.
Kutulutsa Kwambiri Mphamvu 1.029 1mm
Zida za Laser Zopopera Diode
Zida Processing, kuwotcherera ndi kudula
