文摘

class="label">•: Laser interference patterning is introduced to generate sub-micrometer surface pattern.
class="label">•: The two-temperature model is applied to ps-laser interference patterning of metals.
class="label">•: Line-like structures with a pitch of 0.7 μm were fabricated on SAE 304, Ti and Cu.
class="label">•: The process is governed by a photo-thermal mechanism for a pulse duration of 35 ps.
class="label">•: A “cold”-ablation process for metals requires a pulse duration shorter than 10 ps.
