Qeybaha Deynics ee dhexdhexaadka dhexdhexaadka ah
The gain medium is where the fundamental process of light amplification occurs, a phenomenon deeply rooted in quantum mechanics. Is dhexgalka u dhexeeya dawladaha tamarta iyo walxaha dhexdooda dhexdhexaadka ah waxaa xukuma mabaadii'da qulqulka dhiirigelinta iyo furfurista dadweynaha. Xiriirka muhiimka ah ee ka dhexeeya xoojinta iftiinka (i), xoojinta bilowga (I0), qeybta kala-guurka-qaybta (N2 iyo N1) waxaa lagu sharaxay isla'egta I = I0E ^ (n2-n1) l). Gaarista isgaarsiinta dadka, halkaasoo n2> n1, ay muhiim u tahay cod-weyne oo ay tahay aas asaasi ah fisikiska laser1].
Saddex-heerjo vs. afar-heer ah
Naqshadeynta laser-ka laser, saddex-heer iyo afar-heer afar-heer ah ayaa badanaa la shaqeeyaa. Three-level systems, while simpler, require more energy to achieve population inversion as the lower laser level is the ground state. Nidaam afar-heer ah, dhinaca kale, sii wado wax ku ool ah oo loo maro isbarbardhiga dadka sababtuna tahay suuqa degdegga ah ee tamarta, taasoo ka dhigeysa inay ka badan yihiin arjiyada casriga ah ee laser.2].
Is mid dhexdhexaad ah?
Yes, erbium-doped glass is indeed a type of gain medium used in laser systems. In this context, "doping" refers to the process of adding a certain amount of erbium ions (Er³⁺) to the glass. Erbium waa mid naadir ah oo dhulka ah, markii lagu daro marti-galka galaas, waxay si wax ku ool ah ugu dhexgali kartaa iftiinka iyada oo loo marayo kicinta, hanaan aasaasi ah oo ku saabsan hawlgalka laser.
Erbium-doped glass is particularly notable for its use in fiber lasers and fiber amplifiers, especially in the telecommunications industry. Waxaa si fiican ugu habboon codsiyadan sababta oo ah waxay sifiican ugu sii kordhisay iftiinka hirarka illaa 1550 nm, oo ah mawjad fure u ah isgaarsiinta fin-ga ee indhaha oo ay ugu wacan tahay khasaaraha silica ee caadiga ah.
-Ga / -daerriumlaser diode) oo ay ku faraxsan yihiin dowladaha tamar sare. Markay ku laabtaan gobolka tamarta hoose, waxay ka soo saaraan sawirro mawjad gorgortan, taasoo gacan ka geysanaysa hawsha laser. Tani waxay ka dhigeysaa muraayadda cudurka qalalan ee erbium-ka si firfircoon oo dhexdhexaad ah oo si ballaaran loo isticmaalo oo loogu talagalay laser kala duwan iyo comir badan.
