Notes:
The effects of an Nd:YAG laser interaction with titanium target using laser radiation atwavelengths 1.064 or 0.532 μm (40 picoseconds pulse duration) were studied. Modification oftarget surfaces at laser energy densities of 2.4 and 10.3 J/cm2 (λ1laser= 1.064 μm) and 1.1 J/cm2(λ2laser= 0.532 μm) are reported in this article. Qualitatively, the titanium surface modification canbe summarized as follows: (i) ablation of the titanium surface in the central zone of the irradiatedarea for both laser wavelengths; (ii) appearance of a hydrodynamic feature like resolidified dropletsof the material (λ1laser= 1.064 μm), as well as formation of the wave-like microstructures (λ2laser=0.532 μm); and (iii) appearance of plasma, in front of the target, with both laser wavelengths
