Abstract: Diamond has the highest thermal conductivity among known materials, and as such finds uses as an industrial tool in areas where dissipation of excess heat is a requirement. In this investigation we set up a laser system to heat a diamond sample by linear absorption of the laser radiation by the sample. To heat a diamond to high temperature, the laser system should have sufficiently good power stability, beam position and suitable wavelength for absorption The temperature is then measured during the heating process by measuring the thermal radiation spectrum of the sample and using the Planck radiation function. Such a system is the first step in an ultimate aim of determining the temperature induced defects in industrial diamond
