  • Two-photon-polymerization laser direct writing system based on acousto-optic deflector
    Patent number: 11982945
    Abstract: A two-photon-polymerization laser direct writing system based on an acousto-optic deflector is provided, which includes an ultrafast laser device, a beam expander, a scanning field center angular dispersion compensator, a two-dimensional acousto-optic deflector, a scanning field edge angular dispersion compensator, an astigmatism compensator and a focusing objective lens, the ultrafast laser device is configured to emit an ultrafast laser; the scanning field center angular dispersion compensator is configured to conduct precompensation on an angular dispersion at a center of a scanning field; the two-dimensional acousto-optic deflector is configured to deflect the ultrafast laser on the angular dispersion at the center of the scanning field; the scanning field edge angular dispersion compensator is configured to compensate for an angular dispersion at an edge of the scanning field; the astigmatism compensator is configured to compensate for astigmatism; the focusing objective lens is configured to conduct tig
