Ni ukubera ko igikoresho cyimashini (gusa kumashini zikoresha lazeri zifite ingufu nyinshi) ntikoresha guturika no gucukura kugirango habeho umwobo muto, ariko gucukura pulse (poncure yoroheje), bigatuma ingufu za laser nazo ziba mukarere gato.
Agace kadatunganijwe nako kazatwikwa, gatera guhindura umwobo kandi bigira ingaruka kumiterere yimikorere.
Muri iki gihe, dukeneye guhindura uburyo bwo gutobora imitsi (poncure yoroheje) muburyo bwo gutobora (gutobora bisanzwe) mugikorwa cyiterambere kugirango dukemure ikibazo.
Kurundi ruhande, kumashini yo gukata laser yo hasi, gucukura pulse bikoreshwa mugukora umwobo muto kugirango uburinganire burangire.
