Igwe ngbanwe pico nke abụọ q nwere ike ibugharị igwe

N'iji mmetụta mgbawa ọkụ, laser dị elu na-abanye n'ime epidermis ma nwee ike iru ụyọkọ pigmenti na oyi akwa dermis. N'ihi na ike nwere obere oge nke ime ihe na ike dị oke elu, ụyọkọ pigmenti ga-agbasa ngwa ngwa ma gbasaa mgbe ha nwetasịrị ike dị elu n'otu ntabi anya. Mgbe macrophages loro ihe ndị ahụ, pụta, na pigmenti ahụ ji nke nta nke nta na-apụ n'anya.

Laser picosecond nwere obosara usu dị mkpụmkpụ nwere ike mepụta nsonaazụ foto-arụ ọrụ nke ọma ma mebie irighiri pigmenti n'ime obere iberibe.
E jiri ya tụnyere nano-scale Q-switched laser, picosecond laser chọrọ naanị ume dị ala iji nweta mmetụta ahụ.
Ọ na-ewe obere usoro ọgwụgwọ iji nweta mmetụta ọgwụgwọ ka mma.
E nwekwara ike wepụ tattoos ndị isi ike na-acha akwụkwọ ndụ akwụkwọ ndụ na-acha anụnụ anụnụ.
A na-agwọta igbu egbugbu mana ezughị ezu, laser picosecond nwekwara ike ịgwọ ya.
N'ime usoro mbibi nke urughuru pigmenti, enwere mmetụta nke photothermal na photomechanical. Ka obosara nke usu dị mkpụmkpụ, mmetụta nke ịtụgharị ọkụ n'ime ọkụ na-esiwanye ike. Kama nke ahụ, a na-eji mmetụta photomechanical eme ihe, ya mere picoseconds nwere ike ịkụpịa ihe ndị dị na pigmenti nke ọma, na-eme ka mwepu pigmenti dị mma.
