Acousto-optic modulation device |
摘要 |
An acousto-optical modulation device comprises a plurality of acousto-optic modulators arranged in series with each other, to receive a zero-order light from a previous stage of the modulators. A zero-order light emerging from the last stage is used as a modulated light of an incident light. The coefficient of extinction for the zero-order light is raised by this structure, and the acousto-optic modulation device presents a high diffraction efficiency and a high value of the coefficient of extinction at the same time.
