Abstract
Results are presented from experiments on monitoring laser-induced processes (heating, melting, and ablation) on surfaces of carbonaceous materials (glassy carbon, pyrocarbon) using a laser display and according to the brightness temperature determined during these processes with a high-temperature pyrometer. The melting brightness temperature of glassy carbon (2720 ± 15 K) is determined using a continuouswave fiber laser. Some wave structures are revealed. No melting of pyrocarbon was observed over the range of powers and temperatures. The surfaces ablated after heating.
