Makristasi a laser ndi zigawo zake ndizofunikira kwambiri pamakampani opanga ma optoelectronics. Ndiwonso gawo lalikulu la ma lasers olimba kuti apange kuwala kwa laser. Poganizira za ubwino wa mawonekedwe abwino a kuwala, makina abwino, kukhazikika kwa thupi ndi mankhwala, komanso kutentha kwabwino, makhiristo a laser akadali zida zodziwika bwino zama lasers olimba. Chifukwa chake, amagwiritsidwa ntchito kwambiri m'mafakitale, zamankhwala, kafukufuku wasayansi, kulumikizana ndi mafakitale ankhondo. Monga laser kuyambira, laser chandamale chizindikiro, laser kuzindikira, laser chodetsa, laser kudula processing (kuphatikiza kudula, kubowola, kuwotcherera ndi chosema, etc.), laser mankhwala, ndi laser kukongola, etc.
Laser imatanthawuza kugwiritsa ntchito tinthu tambirimbiri tomwe timagwira ntchito munyengo yosangalatsa, komanso kugwiritsa ntchito kuwala kwakunja kuti tinthu tating'onoting'ono tambiri tomwe tili mumkhalidwe wosangalatsa timalize kutulutsa kolimbikitsa nthawi imodzi, ndikupanga mtengo wamphamvu. Ma laser ali ndi mayendedwe abwino kwambiri, monochromaticity ndi mgwirizano, ndipo potengera mawonekedwe awa, amagwiritsidwa ntchito kwambiri m'mbali zonse za anthu.
Ma kristalo a laser amakhala ndi magawo awiri, imodzi ndi ion yolumikizidwa ngati "luminescence center", ndipo inayo ndi kristalo wokhala ngati "chonyamulira" cha ion yolumikizidwa. Chofunikira kwambiri pakati pa makhiristo omwe ali nawo ndi makristasi a oxide. Makristalowa ali ndi maubwino apadera monga malo osungunuka kwambiri, kuuma kwakukulu komanso kuwongolera kwamafuta abwino. Pakati pawo, ruby ndi YAG amagwiritsidwa ntchito kwambiri, chifukwa zofooka zawo za lattice zimatha kuyamwa kuwala kowoneka mumtundu wina kuti ziwonetse mtundu wina, potero kuzindikira oscillation ya laser.
Kuphatikiza pa ma lasers amtundu wa kristalo, ma kristalo a laser akukulanso mbali ziwiri: ultra-large ndi Ultra-zing'ono. Ultra-lalikulu kristalo lasers makamaka ntchito laser nyukiliya maphatikizidwe, laser isotope kupatukana, laser kudula ndi mafakitale ena. Ma laser ang'onoang'ono a kristalo makamaka amatanthauza ma semiconductor lasers. Ili ndi ubwino wa kupopera kwakukulu, kutentha pang'ono kwa kristalo, kutulutsa kokhazikika kwa laser, moyo wautali, ndi kukula kochepa kwa laser, kotero ili ndi chiyembekezo chachikulu chachitukuko pa ntchito zinazake.
