  We are proposing a novel method of laser heating control only through change
in polarization of the incident light, keeping its power density constant. The
idea combines antenna effect found in isolated multi-walled carbon nanotubes
and the possibility of their heating by light illumination. To observe this we
used Raman spectroscopy technique, where the heating manifests itself in a
pronounced downshift of the Raman G and 2D lines as a function of the
polarization angle. Our method can be useful in field electron emission devices
or in selective nanotubes heating and destruction. It can also be extended to
other one dimensional nanoobjects, if only certain conditions are fulfilled.
