2:00 – 3:00 pm Applications of Ultrafast Fiber Laser in Material Processing

Bing Liu, Yuki Ichikawa, Makoto Murakami, IMRA America, Inc., Ann Arbor, MI

Abstract:  After more than 15 years of research and development, IMRA America Inc. has delivered a family of ultrashort pulsed fiber lasers with MHz repetition rates for material applications. This presentation will summarize a few recent research works on applying IMRA’s fiber lasers in material processing. The related applications are mostly based on laser-induced surface modification effects: including (i) femtosecond-laser-induced periodic surface structuring, (ii) laser-induced backward transfer for printing on transparent medium, and (iii) laser-induced super-hydrophobicity on metal and dielectric surfaces that mimics nature’s ‘lotus effect’.

In the above applications, a high pulse repetition rate in the MHz range plays a critical role, not only providing a high process speed, but also altering the underlying laser ablation mechanisms. The ultrashort pulse duration (600 fs) enables low pulse energy processing that improves spatial precision and reduces heat damaging. At near (and above) ablation threshold, femtosecond laser pulses also produces nanometer-scaled morphological features not only on the surface of the work pieces but also in the ablated materials.

By combining the above factors, we further demonstrate another technique of ultrafast fiber laser for material processing, that is fine tuning the processes with manipulating the time sequence of pulse train, in particular, by grouping the pulses into bursts with a short pulse separation of a few tens of nanoseconds between pulses.

In summary, we will demonstrate ultrafast fiber laser as a unique tool in industrial laser material processing that can provide advantages in process speed, spatial precision, controllability and robustness.

Abstract: We discuss random evolution of conical micro-scale spikes on steel surface under femtosecond irradiation with near threshold fluence at high repetition. A possible mechanism for micro-needle formation is discussed. Compared to conical spikes formed through surface evolution with higher fluence, the resulting spikes have characteristics of lower apex angles and non-uniform distributions. High resolution Electron Microscope data will also presented to show their nanometer level morphology.

Both hydrophilic and hydrophobic surfaces are demonstrated on stainless steel (316L) by creating conical microneedles on the surface with femtosecond laser irradiation in air. The scan speed is found to be an effective parameter controlling the cone number density and the contact angle. It was found that the contact angle of water ranges from 0° (superhydrophilic) to 113° on the laser microstructured surfaces depending on the processing conditions. Also we demonstrate superhydrophobicity (~150°) by silane coating on the hydrophobic surface geometry.
