Find out what your object strongly absorbs and chose that wavelength. Reread what I posted.
For example if something is colored red you likely don't want to use a red laser to heat it as it will reflect most of the energy but that same object might be "black" ie absorbs strongly to IR or Blue light.
Shine a blue light on a red ball. It appears black. It absorbs the energy.
