	There are some light-steering possibilities in propogation
of light through a medium (vacuum won't do).  The Kerr effect,
for one, changes the deflection of a particular polarization of
light as it goes through a prism (and with enough reflections through
the prism, it might just give some deflection angle that could be
useful).  The problem can also be solved by vibrating a mirror in
front of the laser, but it's not as safe and easy as a cathode ray
tube.  The Kerr effect is typically employed for Q-switching
lasers (i.e. detuning them) and uses a high voltage to get some
substantial effect; the inside of a TV has high voltages at the
scanning frequency anyway...
