We investigate laser heating of double wall carbon nanotubes deposited on surfaces and immerged in liquids as a function of laser wavelength. Observing the Raman spectrum we find that laser heating of agglomerated double wall carbon nanotubes is six times larger at 488 nm than at 647 nm. The wavelength dependence of the Raman G band is linear in the visible spectral range. The frequency shift of the Raman G band obtained in methanol as a function of temperature is close to what is observed for graphite
