Opto-optical modulation in N-(p-methoxybenzylidene)-p-butylaniline.
A method of opto-optical modulation in liquid crystals is reported. An Ar(+) laser beam is employed to modulate a second He-Ne laser. The highest frequency achieved was 1.5 x 10(3) pulses per second with input modulating powers smaller than 10 mW. A homeotropic N-(p-methoxybenzylidene)-p-butylaniline liquid-crystal cell was employed as the nonlinear medium.
