Table 4.

Approximate depths of the deepest structures on steel and titanium measured by AFM. The structures 2-5 and 5-5 show multiple depths due to the multiple laser radiation in certain areas.

Material	Structure 1-5	Structure 2-5	Structure 5-5
Stainless Steel	880 nm	750 and 990 nm	1050, 1300 and 1400 nm
Titanium	700 nm	400 and 600 nm	900, 1200 and 1300 nm
