▎ 摘　　要

NOVELTY - The device has a main body provided with a saturable absorber material that is formed with a thin film. A film-coating substrate is formed with an electron beam lithography. The electron beam lithography is connected with a rotating support device. A paramagnetic outlet is connected with multi-wall carbon nanometer tubes. A saturable absorber material is provided with graphite and graphene oxide. USE - Optical anisotropic saturable absorber device. ADVANTAGE - The device has high stability, high voltage and wide wavelength range, and controls output polarization state. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparation of an optical anisotropic saturable absorber device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an optical anisotropic saturable absorber device.
