“…For optically thick lines, the thermal radiation heat transfer can be approximated by [30] for a purely reflective sample surface, which is a good approximation for copper at the wavelengths of thermal raidiation. The continuum thermal radiation heat transfer, which is always optically thin for our conditions, can be expressed as , v con ε is the spectral emission coefficient due to continuous emission.…”

A study was made of the cooling of the laser induced vapor plume in background air.The temperature and size variations of the vapor plume were determined from spectroscopic measurements during the first few tens of micro-seconds after the laser pulse. Experiments were carried out over a range of laser spot sizes and energies ------------------------------------------------------------------------------------------- Keywords Laser ablation, plasma cooling, thermal radiation decrease of the vapor plume was independent of the plume size, shape, and position. For 1 larger optical thicknesses of the vapor plume, the calculations showed that the reflectivity of the sample surface and the size of the vapor plume would dramatically affect cooling of the vapor plume.2
