文摘
- •
This work is focused on the formation of laser-induced marks in transparent polymers activated by light-absorbing microparticles.
- •
White- and dark-colored marks have been observed.
- •
Generation of laser-induced marks is accompanied by laser-induced incandescence.
- •
Laser-induced incandescence of laser-heated objects provides information about processes that occur in material substance under laser irradiation.
