Abstract
A device for fabricating a quartz microfluidic chip by a femtosecond pulse cluster. The device includes: a femtosecond pulse cluster laser source configured to output a femtosecond pulse cluster; a beam splitting and interference system, configured to split the femtosecond pulse cluster into a plurality of parts, and to converge split parts to form a femtosecond pulse cluster plasma or a femtosecond pulse cluster plasma grating; a sample system configured to move the electronic displacement platform where a quartz glass is placed to control a position where the parts of the femtosecond pulse cluster are converged on the quartz glass; and a hydrofluoric acid immersion system configured to immerse the quartz glass in a diluent hydrofluoric acid solution to remove an ablated part of the quartz glass to form the quartz microfluidic chip.
