Abstract
A device and a method for direct printing of a microfluidic chip based on a large-format array femtosecond laser. The large-format array femtosecond laser with multi-parameter adjustable laser beam state is used to achieve large-format laser interference. The interference state, interference combination and exposure mode of the large-format array femtosecond laser are regulated, and multiple exposures are superimposed to output the desired pattern for the microfluidic chip, enabling the direct printing processing of the microfluidic chip.
