Summary: electric deflection of light possible Keywords: Kerr effect, nonlinear optics Message-ID: <1208@milton.acs.washington.edu> Date: 2 Jan 90 01:38:25 GMT References: <6220004@hpcupt1.HP.COM> Reply-To: whit@milton.acs.washington.edu (John Whitmore) Organization: University of Washington, Seattle Lines: 14 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... I am known for my brilliance, John Whitmore by those who do not know me well.
