“…A femtosecond (fs) laser, with high peak power and short pulse width, is an on-site processing method that is able to directly create precise micro/nanostructures on almost any material [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. Moreover, the process is simple and highly controllable, making it a powerful technique for the construction of SLIPS substrates [ 7 , 31 , 32 , 33 , 34 , 35 ]. Herein, we converted a Gaussian laser beam to the Bessel profile, and the continuous laser pulses were transformed into pulse trains through a method of pulse shaping.…”
