  We discuss a photon collider based on the $e^+e^-$ \ linear collider with
energies of $2E = 1\div 2$ TeV in cms (ILC, CLIC, ...). Previously, this energy
range was considered hopeless for the experiment in the foreseeable future. We
discuss the realization of the TeV PLC based on modern lasers. A small
modification of the laser-optical system prepared for the photon collider with
energy of $E \approx 250$ GeV will be sufficient if the parameters are chosen
optimally. The high-energy part of the photon spectrum does not depend on
design details and is well separated from the low-energy part. That is a narrow
band near the upper boundary, about 5\% wide. The high-energy integrated \ggam
luminosity is about 1/5 and the maximum differential luminosity is about 1/4 of
the corresponding values for the photon collider with $E \approx 250$ GeV.
