1. Gwiritsani ntchito utali wolunjika kuti muyimbe pamalo enaake: Utali uliwonse wa focal uli ndi utali wake. Ngati kutalika kowerengeka sikuli kolakwika, zotsatira zojambulidwa sizikhala zofanana.
2. Bokosilo limayikidwa pamalo okhazikika kuti galvanometer, galasi lakumunda ndi tebulo lochitirapo zisakhale zofanana, chifukwa ndodo ndi zotulukapo zidzakhala ndi kutalika kosiyana, zomwe zimapangitsa kuti mankhwalawa akhale osagwirizana.
3. Thermal lens phenomenon: Pamene laser ikudutsa mu lens optical (refraction, reflection), lens imatenthetsa ndipo imayambitsa kuwonongeka pang'ono. Kupindika uku kumapangitsa kuwonjezereka kwa kuyang'ana kwa laser komanso kufupikitsa kutalika kwapakati. Makinawo atayima ndipo mtunda umasinthidwa kuyang'ana, laser ikayatsidwa kwakanthawi, kachulukidwe kamphamvu ka laser kamene kamagwira pa zinthuzo kumasintha chifukwa cha chodabwitsa cha magalasi otenthetsera, zomwe zimapangitsa kuti pakhale zosagwirizana zomwe zimakhudza kugoletsa. .
4. Ngati, pazifukwa zakuthupi, katundu wa batch wa zipangizo sizigwirizana, zotsatira zake za thupi ndi mankhwala zidzakhalanso zosiyana. Zinthuzo zimakhudzidwa kwambiri ndi kuyankha kwa laser. Nthawi zambiri, chikoka cha chinthu chimakhala chokhazikika, koma zinthu zosagwirizana ndizomwe zimayambitsa kuwonongeka kwazinthu. Zotsatira zake ndizokondera chifukwa mtengo wa laser mphamvu zomwe chilichonse chingalandire ndizosiyana, zomwe zimapangitsa kuti pakhale kusagwirizana kwazinthu.
