The design and performance of a miniaturized magneto-optic probe using a terbium doped paramagnetic glass are described. The compactness and simplicity of the device are achieved by using the polarizer sheets obtained from a commonly available liquid crystal display. Plastic optical fibers are used to transport the light. A pulsed magnetic field up to 48 T has been generated and measured using high-voltage capacitor discharge in single-turn coils. A rise time and magnetic field-dependent anomalous behavior is observed in the terbium glass characteristics at room temperature.
