AI Technical Summary
Existing femtosecond laser processing technology suffers from low precision and low efficiency when processing complex structures, especially due to the cumulative error and insufficient processing efficiency caused by the limited multi-axis motion platform and scanning rate.
A laser three-dimensional volume manufacturing device is adopted, including a beam positioning unit, a dispersion compensation unit, an acousto-optic modulation unit, and an optical relay compensation unit. By adjusting the spatial position and energy distribution of the beam, the acousto-optic modulation unit divides the laser into multiple sub-beams, and the micro-focusing unit achieves precise focusing, thus avoiding dependence on a multi-axis motion platform.
It improves the precision and efficiency of laser processing, reduces the thermal effect on the material surface, lowers roughness, enables efficient three-dimensional processing of complex structures, and reduces cumulative errors and focal position errors inside the material.
