Kiristaalo laysar ah iyo agabyada matrix-ka asaasiga ah ee laysarka adag:
Codsiyada Muhiimka ah: Lu₂O₃ waa agab muhiim ah oo lagu bilaabo soo saarista kiristaalo laysar oo waxqabad sare leh sida lutetium-doped yttrium aluminium garnet iyo lutetium-doped yttrium lithium fluoride. Kiristaalo-yadan waxaa badanaa lagu muujiyaa Lu: YAG (Yttrium Aluminium Garnet) ama Lu: YLF (Yttrium Lithium Fluoride).
Habka ficilka: Aayooyinka Lutetium (Lu³⁺) laftooda badanaa looma isticmaalo sidii aayooyinka firfircoon (xarumaha qiiqa laysarka). Si kastaba ha ahaatee, iyadoo qayb ka ah shabagga matrix-ka, waxay bixin karaan jawi shabag ah oo aad u deggan oo is haysta. Marka lagu daro aayooyinka kale ee dhulka naadirka ah (sida Nd³⁺, Yb³⁺, Er³⁺, Tm³⁺, Ho³⁺), kiristaalada ku salaysan Lu₂O₃ waxay muujiyaan:
Gudbinta kulaylka oo sareysa: Si wax ku ool ah ayuu u kala firdhiyaa kulaylka, taasoo u oggolaanaysa shaqada laysarka awoodda sare leh iyo yaraynta saameynta muraayadaha kulaylka.
Xasillooni sare oo kiimiko iyo farsamo: Hubi isku halaynta muddada dheer ee laysarka jawi adag.
Sifooyinka tamarta phonon ee aadka u fiican: Waxay saameysaa cimriga heerka tamarta iyo hufnaanta ion-yada laysarka.
Codsiyada: Laser-yadan waxaa si weyn loogu isticmaalaa farsamaynta walxaha warshadaha (jarista, alxanka, calaamadaynta), caafimaadka (qalliinka indhaha, daaweynta maqaarka), cilmi-baarista sayniska, lidar, iyo cilmi-baarista isku-dhafka xannibaadda ee suurtagalka ah.

Muraayadani waxay lagama maarmaan u tahay sixitaanka kala-goysyada chromatic ee nidaamyada indhaha ee horumarsan (sida ujeedooyinka mikroskoobka, muraayadaha kamaradaha ee heerka sare ah, iyo nidaamyada lithography).
Dhoobada hufan: Lu₂O₃ lafteeda ama marka lagu daro oksaydhyada kale (sida Y₂O₃) waxaa loo isticmaali karaa in lagu sameeyo dhoobo polycrystalline ah oo hufan. Dhoobadani waxay leeyihiin isku midnimo muuqaal ah iyo gudbin iftiin oo la mid ah kiristaalo keli ah, laakiin way ka weyn yihiin cabbirkooda, xooggooda farsamada way ka sarreeyaan, waxaana laga yaabaa inay ka jaban yihiin diyaarinta.
