Co: Crystals Spinel
Q-switches dadban ama kuwa nuugi kara waxay dhaliyaan garaaca leysarka awood sare iyadoo aan la isticmaalin koronto-optic Q-switchs, taas oo hoos u dhigaysa cabbirka xirmada iyo baabi'inta koronto sare.Co2+:MgAl2O4 waa shay cusub oo loogu talagalay beddelashada Q-dabacsan ee leysarka ka soo baxaya 1.2 ilaa 1.6μm, gaar ahaan, isha-ammaan 1.54μm Er: leysarka muraayadda, laakiin sidoo kale ka shaqeeya 1.44μm iyo 1.34μm laser hirarka.Spinel waa crystal adag, xasilloon oo si fiican u dhalaalaysa.Cobalt waxay si diyaar ah ugu beddeshaa magnesium ee martida loo yahay Spinel iyada oo aan loo baahnayn ions magdhow dheeraad ah.Qaybta nuugista sare ee iskutallaabta (3.5 × 10-19 cm2) waxay oggolaataa Q-beddelka Er: leysarka muraayadda iyada oo aan la isku dhejin oo diiradda saareysa labadaba flash-laambad iyo bamgareynta laser diode.Natiijooyinka nuugista gobolka ee xiisaha badan waxay keenaysaa isbarbardhigga sare ee Q-switch, ie saamiga bilowga (calaamadaha yar) iyo nuugista buuxda ayaa ka sarreysa 10.
