Laser-induced incandescence of carbon surface: a method for temperature estimation

摘要

Laser-induced incandescence (LII) of carbon surface is investigated with 1.06 μm YAG:Nd~(3+) pulsed laser excitation. The experiments show that the intensity of LII of carbon surface depends on the initial temperature of the investigated sample. A method is proposed for estimation of temperature of laser-heated surfaces. The method requires measurement of LII at a fixed wavelength with a moderate variation of initial sample temperature.
