Abstract

It is well known that femtosecond laser filamentation can be initiated by ultrashort laser pulses in condensed media. The supercontinuum generation was studied with the generated white light ranging from 400 to 950 nm in nanoparticle-doped water. We summarized the motion of the generated bubbles. The velocity of the bubble reached 0.16 m/s, and it means that the water flow can also reach the corresponding speed. This could be a potential technique for microfluidic chip fabrications.
