Erbium Glass Micro laser
Sharaxaada Alaabta
1535nm ultra-yar erbium galaas indho-ammaan ah leysarka gobolka adag waxaa loo isticmaalaa kala duwanaanshaha laser, iyo 1535nm hirarka waa kaliya booska isha aadanaha iyo daaqada atmospheric, sidaas darteed waxa ay heshay fiiro gaar ah beeraha kala duwan ee laser. iyo isgaarsiinta elegtarooniga ah. Laysarka dhalooyinka Erbium ee heerka celceliska garaaca wadnaha hooseeya (in ka yar 10hz) kala duwanaanshaha laser. Laysaradayada indhaha-ammaan ah ayaa loo adeegsaday shaybaarayaal kala duwan oo leh masaafo dhan 3-5km iyo xasillooni sare oo loogu talagalay beegsiga madaafiicda iyo meelaha aan duuliyaha lahayn.
Marka la barbar dhigo leysarka caadiga ah ee Raman iyo OPO (Optical Parametric Oscillation) lasers kuwaas oo dhaliya hirarka indhaha-ammaan ah, laysarka muraayadda sedku waa walxo shaqeynaya kuwaas oo si toos ah u dhaliya hirarka badbaadada indhaha, waxayna leeyihiin faa'iidooyinka qaabdhismeedka fudud, tayada iftiinka wanaagsan, iyo kalsoonida sare. Waa isha iftiinka ee la door bidayo ee indho-indhaynayaasha badbaadsan.
Laser-ka ku sii daaya hirarka hirarka ka dheer 1.4 um ayaa inta badan loo yaqaan "indhaha badbaadsan" sababtoo ah iftiinka xadka hirarkan waxa uu si xoog leh u nuugaa cornea iyo lenska isha sidaas darteed ma gaari karo xuubka isha ee xasaasiga ah. Sida iska cad, tayada "badbaadada indhaha" kuma xirna oo kaliya mawjadaha sii daaya, laakiin sidoo kale heerka awoodda iyo iftiinka iftiinka oo gaari kara isha. Laysarka badbaadada indhaha ayaa si gaar ah muhiim ugu ah 1535nm laser kala duwan iyo radar, halkaas oo iftiin u baahan yahay inuu u safro masaafo dheer dibadda. Tusaalooyinka waxaa ka mid ah qalabka kala duwan ee laser-ka iyo isgaarsiinta indhaha ee meel bannaan.
