1535nm Er, Cr, Yb: galasi la phosphate
Er, Cr, Yb phosphate galasi ndiye zopangira zopangira ma kristalo olimba ang'onoang'ono a ma lasers opopa, ma erbium-doped concentration ndi 0.13cm³～0.25cm³, ndipo mphamvu yotulutsa kuwala imachokera ku millijoule mpaka mulingo wa joule.Erbium Glass yopangidwa ndi Er3+, Yb3+ ndi Cr3+, Erbium doped glass laser imapereka gwero lothandizira logwirizana pamtundu wa spectral pafupi ndi 1.5 μm, yomwe ili yotetezeka kwa diso la munthu ndipo ndiyosavuta kugwiritsa ntchito zambiri, monga Lidar ndi miyeso yosiyanasiyana, fiber. -Optic kulankhulana, ndi opaleshoni laser.Ngakhale pali kupita patsogolo kwakukulu pakupanga magwero a mapampu a laser diode a InGaAs, tochi ya Xe ipitiliza kugwiritsidwa ntchito ngati magwero a pampu a Er: lasers yamagalasi chifukwa chodalirika komanso kutsika mtengo, komanso kuphweka kwamapangidwe a makina otere.Popeza pafupifupi theka la mphamvu ya radiation ya tochi imachokera m'magulu owoneka ndi pafupi ndi infrared (IR), chodziwitsira chachiwiri Cr3+ chimalowetsedwa mu magalasi a Yb-Er kuti agwiritse ntchito mphamvuzi.

1535nm Er, Yb phosphate galasi
Kuphatikizika kwa erbium kwa galasi lopopera la LD ndi 0.25cm³～1.3cm³, ndipo mphamvu yotulutsa kuwala imachokera ku microjoule kupita ku millijoule. kutembenuka bwino ndi lalikulu kwambiri mpope gulu.Amagwiritsidwa ntchito kupanga optical waveguide amplifiers ndi lasers.Zinthu zabwino zimatha kukwaniritsa 1535nm laser linanena bungwe.Monga gwero lotetezedwa ndi maso la 1535nm lomwe limapopedwa ndi ma diode a laser, limatha kutulutsa ma radiation otetezedwa ndi maso a 1535nm, omwe angagwiritsidwe ntchito mwachindunji pakuyambira kwa laser komanso kulumikizana patelefoni.Posachedwapa, wakhala akugwiritsidwa ntchito mu optical fiber communication m'malo mwa EDFA chifukwa cha ubwino wambiri.
